That's an interesting question. I'm not sure that there's a simple answer.

I mean if you look like like a man, dress like a man, act like a man, and everyone treats you like a man, then I guess there isn't much difference.

I disagree that we need words for every new complex idea. If the situation becomes common enough, then maybe there should be a term for it, but I don't think that's what you were originally asking...an this can be evidenced by the form of debate you chose. Had you merely been looking for a term you would more then likely have created I popularity contest and not a two-sided debate.

Obviously the main incentive was to make a joke, but it appears that you still want to put this person into one of two easily defined categories. Either she's a man now, or she's a lesbian...and I disagree with that premise.

I'm not saying don't explain it. In fact you already did in the title of this debate. What I'm saying is that sometimes things don't conveniently fit into one of our predefined labels, and it's stupid to force them.

Why do you have to put a label on it?

Why can't it just be?
