Openly gay but dislike (most) gay males?

[Insertnamehere]

It's a different thing for people "not to exist" for you and having animosity towards them. The first indicates indifference and indifference is not animosity.

Animosity means they have an effect on you, ergo, they exist for you.

It's also really telling that you begin your post with saying "almost all gay males" and then say "only the ones I'm attracted to"

I think you may be, unconsciously or not, trying to enact a self defense mechanism here in which anyone who doesn't like you back instantly is a person worthy of your hatred.

Then, the problem is not you, it's them, right? How dare they not like you? And your ego (conscious self, this is) remains mentally healthy.

This is a certain version of a "reaction formation" process: an emotion that is anxiety-inducing (you liking a guy that doesn't like you back), something that your conscious self can't handle, is turned into the opposite emotion to help you deal with it.
