I stole that headline from Andrew Sullivan, because like Andrew, I don't really understand how there can be much debate about Alec Baldwin's tendency to insult people who have angered him with the word "faggot" ("cocksucking fag" to be specific). "Faggot," like most slurs, is a word used to remove a group from the protections of society. It is not incidental that slurs frequently accompany acts of violence—both systemic (withholding the protections of the law) and personal (beatings, torture and killings).
Along with that societal estrangement comes an entire series of justifications—physical weakness and immorality being the main ones. When Baldwin calls someone who has angered him a faggot, he is invoking those justifications. He is saying, "Your behavior is like that of a gay man and you should be treated as such." It is not a mistake that this reaction accompanies a temper bordering on violence.
This is bigotry. And it is not complicated by the fact that Baldwin supports marriage equality. One need not believe that LGBTQ human beings are equal to support their right to marry, any more than one needed to be an anti-racist to support abolition, or an anti-sexist to support women's suffrage. There any number of self-interested reasons to support the advancement of civil rights. "Let them niggers vote" or "let them fags marry" is actually a politically consistent position. It says, "I don't like you, but I'm not willing to put my tax dollars behind my dislike." Or even, "I don't like you, but I think I can profit from taking this position."
This is progress. But it certainly isn't the end of bigotry. And progressives, in this enlightened age, should not be in the habit of handing out cookies to bigots who happen to be politically sophisticated. One of Andrew's commenters begins by claiming that he feels "slimy" defending Baldwin. The commenter then launches a defense of his right to use the word faggot (and nigger) when angered. But if it feels slimy, it almost always is slimy. It is slimy to want credit for recognizing someone else's humanity, while avoiding a confrontation with the standards for your own.
UPDATE: Sorry, but I forgot to quote this essential graff from Andrew:
In my view, the gay rights movement is not, at its core, about enacting legislation, or merely a political struggle. It is a moral case for the equal dignity of gay people, and for mutual respect. What deeply troubles me is not so much that one hot-headed actor is a bigot, but that his public support for gay causes is effectively buying him a right to perpetuate the vilest canards and hatreds that have demeaned gay people for centuries. What disturbs me is that pro forma support for various gay organizations or causes gives this man permission to perpetuate the foulest forms of bigotry – and never take full responsibility for it, and to do it again and again, with no penalty or the faintest sense that he has really done something terribly wrong by his own alleged standards.
