Speaking for myself, and only myself, I think there's a big difference between "If I imagine myself having sex with men, it makes me feel unpleasant and disgusted on a solely personal level, because I'm not attracted to men at all and I would be forcing myself to have sex with people I don't want to" and "I think having sex with men is bad."
Without being as verbose as I have (for example's sake), I think the former can easily be mistaken for the latter. I haven't read any of the posts in this thread as the latter, at least not off the top of my head, and I don't believe that's been anyone's intent. I've seen some good-natured teasing, and some to-the-point questions, but nothing that appears intentionally homophobic or malicious.
At the same time, as I said above, I believe the former example can easily be mistaken for the latter example. I also see how the former example, mistaken for the latter example, may be alarming, unsettling, or disappointing. Do you say something, bringing attention to how you perceived the other person's words, or not?
I think it says something to the maturity, responsibility, and understanding of Susan's Place that we can discuss these things, even if we don't always choose the most "diplomatic" words.
Also, if I've misspoken or offended anyone, please tell me; it is late, I am tired, and today has been simultaneously very good and very stressful.
