Actually, this is a very relevant point, because as I recall, the discussion about the Arab and the Jewish woman (over at Ran's, anyway) focused almost entirely on *her* responsibility to check the facts more carefully if she was that bothered about his race.

In that case, the balance of opinion was very firmly that it was her duty to be more careful about who she slept with if she had lines she didn't want to cross. In this case, you're placing the responsibility entirely on the trans person to either divine whether their partner has such lines, or (more likely) simply to assume that every potential partner has them. So there's a very strong inconsistency there, that the comparison draws out.

Now, of course, the two cases aren't identical. Still, it illustrates the point - merely by *being* a trans person, you're saying , you have to assume that, and behave as if, every potential sexual partner you meet will be revolted by you. I can certainly see why people might find that view upsetting.
