Knowing someone who is a homosexual is not the same as having one as a friend. I actually have a lesbian acquaintance or two, but they’re not friends in the normal sense. I had one over for Thanksgiving one time, and she’s welcome whenever. But I haven’t seen her for several years, and we never palled around. She had her circle of friends separate from me and my friends. I actually have a lesbian co-worker “friend” who is as conservative politically as anyone you could meet. But again, not a real friend (some one you associate with apart from work) but a friendly acquaintance.
I never said knowing, I said friends. We know hundreds maybe thousands, we get at least 100 friends of at least casual nature, and thus will probably have at least 1 or 2 that are gay. It’s just stats.
