There's nothing really wrong with being proud of yourself, but there is a disconnect between being proud of yourself and flaunting and forcing everyone else to acknowledge you, while also lashing out.

I've never been "proud" that I'm straight. I don't see why people should be particularly "proud" that they're gay, either. You can be proud of yourself for being out of the closet, I guess, but why does that have to be advertised so much? I don't have to advertise that I'm straight all over the place. I don't wear a shirt that says "I'm straight", I don't make everyone else acquiesce to my sexuality, etc.

It's just such a strange and inorganic disconnect.
