Answer by taking a quote from the following article:

Andrew Michael Sullivan (born 10 August 1963) is an English-born American author, editor, and blogger. Sullivan is a conservative political commentator, a former editor of The New Republic, and the author or editor of six books. He was a pioneer of the political blog, starting his in 2000. He eventually moved his blog to various publishing platforms, including Time, The Atlantic, The Daily Beast, and finally an independent subscription-based format.

Sullivan, like Marshall Kirk, Hunter Madsen, and Bruce Bawer, has been described by Urvashi Vaid as a proponent of "legitimation", seeing the objective of the gay rights movement as being "mainstreaming gay and lesbian people" rather than "radical social change". Sullivan wrote the first major article in the United States advocating for gay people to be given the right to marry, published in The New Republic in 1989. Many gay rights organisations attacked him for the stance at the time. Many on "the gay left" believed that he was promoting "assimilation" into "straight culture", when the aim of most at that time was to alter codes of sexuality and society as a whole, rather than fitting gays into it. However, his arguments eventually became widely accepted and formed the basis of the modern movement to allow same-sex marriage. In the wake of the United States Supreme Court rulings on same-sex marriage in 2013 (Hollingsworth v. Perry and United States v. Windsor), New York Times op-ed columnist Ross Douthat suggested that Sullivan might be the most influential political writer of his generation, writing, "No intellectual that I can think of, writing on a fraught and controversial topic, has seen their once-crankish, outlandish-seeming idea become the conventional wisdom so quickly, and be instantantiated so rapidly in law and custom."  Sullivan opposes hate crime laws, arguing that they undermine freedom of speech and equal protection. He also opposes the Employment Non-Discrimination Act, arguing that it would "not make much of a difference" and that the "gay rights establishment" was wrong to oppose a version of the bill that did not include protections for gender identity. Sullivan opposed calls to remove Brendan Eich as CEO of Mozilla and argued that "old-fashioned liberalism brought gay equality to America far, far faster than identity politics leftism."  In 2006, Sullivan was named as an LGBT History Month icon.

Did he ever win any awards for his writings?
