Maybe these clients should find another hobby that doesn’t put them at risk of this kind of exposure?1 - The person recounting the story specifically said the crime was commited because someone who was transphobic found out AFTER they had sex, and that was the motive for the crime. How can you say "we just can't know that"? I'm not saying there should be a list, I'm not saying (like the OP did) that it should be illegal. I'm saying that the ethical thing to do is for that person to be upfront.
2 - just because YOU can't see the difference, Charlotte, it doesn't mean everyone feels the same. You are welcome to your view that it wouldn't make a difference to you, but that is clearly (by this thread) that many people feel differently. Everyone should be respected, not just the sex worker. Quite frankly, if that is something they are not willing to publicly disclose, then perhaps they should choose another profession where their rights do not trample the rights of others.
3 - Again throwing out "Trans-phobic" like there is some magical rule that if you don't want to have sex with someone, that makes you "phobic" to them. Once again, I have gay friends who i support fully. And i still don't want to have sex with a man. That doesn't make me homophobic. Similarly, not wanting to have sex with a transexual does not make me trans-phobic. The world is not black and white, there are shades of grey (at least 50, I've heard).
As a client you have the “right,” I guess, to inquire in any way you want before partaking in an exchange. She can lie or mislead you in many ways, and we all agree that it sucks, and many of us have experienced when an ad, or inquiry misleads us into pulling the trigger.
But you have absolutely no real “rights” here in the true sense of the term, except your consumer rights against fraud. The Classifieds section here is full of bait and switch or misleading menus (etc.). It’s the risk we take. If you feel she committed an act of fraud, call the cops, I guess.
Luckily we have TERB, so the same ‘misfortune’ may not happen to two guys.
