No, it's different than that. I'm not asking "are you a twink or a bear" I'm asking if you belong to a group that doesn't identify as homosexual. If you think homosexuality is evil, you probably can still acknowledge that some people do identify themselves as homosexual.

Your point only exists for an extremely narrow group of people who deny that people identify as trans or homosexual. And for those folks, I'd probably have a separate conversation about, "you might consider it amoral, but you know there are people who call themselves gay, right?"
