Allies

I often see people with rainbow or equality stickers that say ALLY across them, and I'm not sure how I feel about them. Here's why: these allies are still "othering" homosexuals, essentially saying "I support them, but don't think I'm one of them." I can understand not wanting to give people the "wrong" idea, but if you truly have no problem with homosexuals, why feel compelled to point out that you aren't one? The only reasons I can think of boil down to fear. What do y'all think? Does this post even make sense?
