No, that would be an incorrect definition. “Phobia” is a condition when you are afraid of something, when something frightens you. This is clearly not the case.
Are you afraid of dung piles? Of rotten fish? Of liquid vomit? Do these things frighten you? Or you’re just disgusted, naturally?
So yes, I’m definitely not afraid of homosexual people. Disgusted, yes - but that’s it.
By the way, you or some other person might be disgusted by MY sexual habits. Or not. Most likely not - because you’d never know them. I have no intention to make them public.
And people who DO have intention to do so, they disgust me. Because of this, not because what they do in the bed.
