William Gheen of Americans for Legal Immigration PAC accused Lindsey Graham of being a Democratic Party puppet because he's afraid the White House will out him. Of course, he has nothing to worry about since we live in a post-gay society and whatever people want to do with their sex lives is their business. No one cares about his sexuality; it's just a coincidence that it's announced at key moments to discredit him. Seriously, what's the fuss?
I'm guessing Gheen doesn't have much respect for Barney Frank, actually. Something tells me that he's not being 100% honest with the crowd.
I also don't think that he could possibly believe that the only problem with Graham's sexuality, if he were gay, is that someone's holding it over him. If Graham came out of the closet, I'll just say right here that I doubt the tea baggers would throw him a parade, complete with rainbow flags and drag queens and pretty boys in their underwear.
They don't think Lindsey Graham is doing their bidding, and like the identity politics warriors they are, they're looking for any reason to kick him out of the Good Ol' Boys Club. Calling him a faggot is easy enough, especially with all the rumors about his sexuality floating around for years.
And, of course, if they're really only worried about gay people having their sexuality held over them, working to end homophobia would be the easiest solution. If people had no reason to fear shame or think they'd lose their jobs if they came out, then there'd be no way to blackmail them.
