It's not merely wrong in my view, it's just logically wrong. You beg the question by assuming as a premise part of your conclusion. "Because being gay and acting gay are separate, one can accept a gay person but reject their actions without being bigoted because they are separate."
I cannot accept that they are different because I do not acknowledge or agree with the notion that the separation upon which the difference relies even exists. Because it doesn't. Your sexuality is not simply who you are or what you are attracted to but also its expression in reality. You're attempting to divorce identity from expression of itself which makes no sense to me. You're simply restating the tired "hate the sin but love the sinner" that all LGBT people have heard all their lives. Go ahead and ask us how often we found that to be as true in practice.
I would very much advise not telling gay people what homosexuaity is and isn't, which you are doing when you try to argue that it's a divided concept that can be partly rejected and reviled.
Because let's make one other thing clear: rejecting the acts and "choices" made to reflect my orientation isn't some harmless opinion like "I didn't like Mad Max Fury Road" (although such people are monsters, clearly.
) It makes it ok to sneer and show disgust at people being same-sex affectionate in public, be ause after al, it's just the act they're rejecting. You wanna know the psychological damage you can do to people by avoiding eye contact at best for holding hands? I know too many gay people who are too afraid to be affectionate in public because of the responses they get.
It's not harmless, and it rejects me as a person.
