I don't think there's anything inherently wrong with showing a little pride for who you are. I mean, shit, wear a button, throw on a tie-dye shirt, and paint a little flag on your cheek or whatever. It just... it has to be in moderation, like anything and everything in this grand current that's our lives. You can kvetch all day about how pride itself is a sin, but it's that same feeling of self-accomplishment and recognition, that despite the world being as malevolent as it is, you're still here. That's worth something.
That being said, as a gaybo myself, I am sincerely pleading for my fellow homos to quit being so fucking insufferable and just enjoy yourselves in a respectable, manageable way.
I just want to hold hands with my bf in a park while eating an overpriced street vendor taco in the summer. Don't ruin that for me by being a faggot.
