Someone I know passed along this meme, and since I didn't have commenter privilege on that post I shared it, with my commentary, and then checked out the proximate source. The comments there were a mixed bag, though it was clear that for many people who liked the meme, antigay bigotry was a significant factor in their opinion.
There are many things I could say, but I think it's best to address this idea directly. First off, I am not surprised that many Homo-Americans have sunk to the level of our worst enemies in reacting to this meme and the whole notion of "straight pride." (One commenter wrote: "Are you Christian? Kill yourself". That's showing your moral superiority!) Haven't we been saying for decades that we're just like straight people except for whom we love? Well, unfortunately, it's true.
I considered pointing out that an analogous "white pride" meme would also go down like a Zeppelin, but then I remembered that people who say they need to celebrate straight pride are likely to be the same people who ask peevishly why there isn't a white history month, so never mind.
However. I'm all in favor of straight pride manifestations. We've had a few "straight pride" events here at IU over the years, though not recently. They were all organized by right-wing groups who were known to embrace antigay bigotry, but since they were not known for thoughtfulness or more than minimal intelligence, this didn't bother me; they were too dull to understand what they were proposing. Again, not all that different from many of my fellow homosexuals, unfortunately.
I love my straight friends and relatives; I don't look down on them, because I know they can't help themselves; they deserve pity and sympathy, not censure. Love the sinner and hate the sin! So whenever I encounter someone talking about "straight pride" events, I tell them that, and I offer to help them organize the "gay allies" contingent. Just as gay pride celebrations routinely include straight allies, often with straight allies as parade marshals, a straight pride celebration should welcome the support of gay allies. I haven't received a very welcoming response when I've made this offer, for some reason. I think it's long past time to organize the first branch of Parents and Friends of Straight People. It sounds like they really need the support!
