Fifi,
thanks. :) I did firmly tell the asshat doctor he was out of line before I left the office. It was infuriating that he assumed I was a neurotic hypochondriac with an eating disorder just because I was a young woman. Like when I said, "look, if you're not going to perform the examination my doctor requested can you at least give me some guidance on what to eat or avoid?" he replied in this dismissive tone, "oh, you shouldn't worry about it, just eat foods you like!". At which point I had to slap my hand on his desk and say "I'm not denying myself food here. I don't have any kind of emotional dysfunction about food. I just want to know how to eat without having blinding pain!" And fortunately my GP was very cool about it. When I told him what happened and he just looked at me silently stunned for a moment, he couldn't believe that one doctor would refuse to conduct an examination that another doctor had specifically ordered. He sent me to someone else who was good.

PaulaC,
I can totally see what you're saying about the gay/buttsex comment and I don't appreciate it when someone uses "fag", "gay" or "pussy" to mean something less-than or derogatory. But I understood the OP to be making a ludicrous anology equivalent to the ridiculous statements the man had been making, such as someone who is not in any way homosexually inclined suddenly deciding to have relationships with men for the purpose of having anal sex. I didn't take it that she was making a disparaging remark about homosexuality, just trying to point out that he was being entirely inappropriate by dishing it back to him. That was my take on it anyway.

He might, but it's kind of like calling him a lady or a asserting he has a vagina between his legs. It helps perpetuate the idea that such things are an insult. Whenever I hear someone refer to another person as a fag, I turn and say 'can you tell me why that is wrong?', they generally have no logical answer. We all have a opportunity to point things out when they happen, if we do so as a population, we have a greater chance to make a change.
