"Oh, so now the name calling can begin. simply because I think you're "joke" was immature and unnecessary then I become homosexual myself and you feel the need to say that I am in fact homosexual?"

I have no way of knowing what Jim might have written in a personal email, but it surely wouldn't have been anonymous as you claim. Knowing Jim for as long as I have, I feel safe in saying that your perception of a threat is misguided. If a physical confrontation was what Jim wanted to convey, he wouldn't mince words.

That really does happen quite frequently at the convention. Nobody is disallowed from talking about the things that face us all in everyday life. Those differences in opinion are what make us all human. Most folks have strong opinions about things. I've met folks in this hobby who have diametrically opposite views from myself on some matters, yet some of them are among what I consider to be very close friends. I think you can find that too, if you will let it happen.
