Some context: Journey is an American rock band that formed in San Francisco in 1973, composed of former members of Santana and Frumious Bandersnatch. The band has gone through several phases; its strongest commercial success occurred between 1978 and 1987. During that period, the band released a series of hit songs, including "Don't Stop Believin'" (1981), which in 2009 became the top-selling track in iTunes history among songs not released in the 21st century. Its parent studio album, Escape, the band's eighth and most successful, reached No. 1 on the Billboard 200 and yielded another of their most popular singles, "Open Arms".
With Cain on board, the band began writing material that would eventually lead up to Journey's biggest studio album, "Escape". Recording sessions began in April 1981, and lasted until the middle of June. Escape was released on July 31, 1981, and immediately the album became a mainstream success. The album, which has thus far sold nine times platinum, went to number one on the album charts later that year, and included three top-ten hits: "Who's Cryin' Now", "Don't Stop Believin'" and "Open Arms". The last is Journey's highest-charting single to date, staying at No. 2 for six consecutive weeks and ranking at No.34 on Billboard's 1982 year-end Hot 100. MTV videotaped one of their two sold-out shows in Houston on November 6, 1981, in front of over 20,000 fans.  Capitalizing on their success, the band recorded radio commercials for Budweiser and sold rights to their likenesses and music for use in two video games: the Journey arcade game by Bally/Midway and Journey Escape by Data Age for the Atari 2600.  This success was met with criticism. The 1983 Rolling Stone Record Guide gave each of the band's albums only one star, with Dave Marsh writing that "Journey was a dead end for San Francisco area rock." Marsh later would anoint Escape as one of the worst number-one albums of all time.  Journey's next album, Frontiers (1983), continued their commercial success, reaching No. 2 on the album charts, selling nearly six million copies. The album generated four Top 40 hits, "Separate Ways (Worlds Apart)", which reached No. 8, "Faithfully", which reached No. 12, "Send Her My Love" and "After the Fall", both of which reached No. 23. By this time, Journey had become one of the top touring and recording bands in the world. During the subsequent stadium tour, the band contracted with NFL Films to record a video documentary of their life on the road, Frontiers and Beyond. Scenes from the documentary were shot at JFK Stadium in Philadelphia, Pennsylvania with more than 80,000 fans in attendance.

Question: Lonnie Rashid Lynn, Jr. was born on March 13, 1972 at the Chicago Osteopathic Hospital in Chicago's Hyde Park neighborhood, the son of educator Dr. Mahalia Ann Hines and former ABA basketball player turned youth counselor Lonnie Lynn Sr. He was raised in the Calumet Heights neighborhood. Lynn's parents divorced when he was six years old, resulting in his father moving to Denver, Colorado. This left Lynn to be raised by his mother; however, his father remained active in his life, and was able to get Lynn a job with the Chicago Bulls as a teenager.

Common was invited by First Lady Michelle Obama to appear at a poetry reading on May 11, 2011 at the White House. His poetry was found to be greatly influenced by Maya Angelou's works. This caused furor with the New Jersey State Police and their union, who disagreed with his lyrical content. The president of the New Jersey State Troopers Fraternal Association voiced concern to the White House. They cite the song "A Song For Assata" about a member of the Black Liberation Army and step-aunt of deceased rapper Tupac Shakur named Assata Shakur, previously known as Joanne Chesimard, who was convicted in 1977 of the first degree murder of New Jersey state trooper Werner Foerster.  At another poetry reading, Common said, "flyers say 'free Mumia' on my freezer", a reference to Mumia Abu-Jamal, who was controversially convicted of killing Philadelphia Police Officer Daniel Faulkner in 1981. Common stated, "The one thing that shouldn't be questioned is my support for the police officers and troops that protect us every day."  Jay Carney, the White House Press Secretary at the time, spoke for President Obama on the matter by saying the president does not support, but actually opposes, some of the kind of words and lyrics that have been written by Common and others. Even though the president does not support the lyrics in question, he believed that some reports were distorting what Mr. Lynn stands for more broadly. Common gave a single line response to the entire controversy: "I guess Sarah Palin and Fox News doesn't like me."  Jon Stewart of Comedy Central's The Daily Show questioned Fox News' coverage of the controversy, saying that they "took the time to ignore Common's entire body of work, save for one poem he wrote in 2007 that they appear to misunderstand." Stewart also pointed out that in 2002, George W. Bush honored Johnny Cash, whose songs contain violent lyrics. Stewart further pointed out that Fox News itself offered positive coverage of Common's career in 2010, and that Sean Hannity, who criticized Common's White House invitation, is a friend of musician Ted Nugent, who in clips played on The Daily Show, used violent rhetoric in comments he made about President Obama and Hillary Clinton. Common later discussed the matter with Stewart during a September 14, 2011 appearance on the program.  In September 2011, Common published his memoir, One Day It'll All Make Sense, through Atria Books. As the book details how his close relationship with his mother influenced his life, it is partially narrated by her.

Using a quote from the above article, answer the following question: Why did Obama care about Common?

Answer: Even though the president does not support the lyrics in question, he believed that some reports were distorting what Mr. Lynn stands for more broadly.

Some context: Stephen Edelston Toulmin (; 25 March 1922 - 4 December 2009) was a British philosopher, author, and educator. Influenced by Ludwig Wittgenstein, Toulmin devoted his works to the analysis of moral reasoning. Throughout his writings, he sought to develop practical arguments which can be used effectively in evaluating the ethics behind moral issues.
By reviving casuistry (also known as case ethics), Toulmin sought to find the middle ground between the extremes of absolutism and relativism. Casuistry was practiced widely during the Middle Ages and the Renaissance to resolve moral issues. Although casuistry largely fell silent during the modern period, in The Abuse of Casuistry: A History of Moral Reasoning (1988), Toulmin collaborated with Albert R. Jonsen to demonstrate the effectiveness of casuistry in practical argumentation during the Middle Ages and the Renaissance, effectively reviving it as a permissible method of argument.  Casuistry employs absolutist principles, called "type cases" or "paradigm cases," without resorting to absolutism. It uses the standard principles (for example, sanctity of life) as referential markers in moral arguments. An individual case is then compared and contrasted with the type case. Given an individual case that is completely identical to the type case, moral judgments can be made immediately using the standard moral principles advocated in the type case. If the individual case differs from the type case, the differences will be critically assessed in order to arrive at a rational claim.  Through the procedure of casuistry, Toulmin and Jonsen identified three problematic situations in moral reasoning: first, the type case fits the individual case only ambiguously; second, two type cases apply to the same individual case in conflicting ways; third, an unprecedented individual case occurs, which cannot be compared or contrasted to any type case. Through the use of casuistry, Toulmin demonstrated and reinforced his previous emphasis on the significance of comparison to moral arguments, a significance not addressed in theories of absolutism or relativism.
