Mumei's argument was basically that not wanting to fuck dudes made you a bigot.
It's not the single craziest Social Studies Warrior argument I had ever seen, but it's up there.
Also, giving someone AIDS on purpose is terrible and such an action warrants prison so the crazy fucker (pun not intended... I think) doing it is stopped. Even if the incident rate is low, there's nothing inherently wrong with a criminal law that doesn't see much use.
Transgender women are women
AIDS is not HIV.
But I know where arguing with you goes -- endless tedium.
"Transgender women are..." folks who if you want to have sex with, more power to you, but a lot of dudes don't want to, and that's okay, and not rationally worthy of condemnation, in the same way wanting to isn't. Mumei's argument was that not wanting to fuck humans with a Y chromosome is to be bigoted against them.
Also, semantics about HIV and its end stage does not help produce a counter argument to the moral, civil, and criminal liability of deliberately infecting someone with a disease that will eventually kill them and in the meantime require exceedingly expensive medications for the remainder of their life.
Sex isn't rational to begin with. You're sticking your penis in a hole, and this is for some reason the most amazing thing imaginable. It's just a hole. Why not any other hole? Why not oil up a rubber tube and go to town on it? Okay, I admit I already do that, but you know, You're doing it imagining it is a vagina.
When you think of it like that, you can see that it makes no sense outside of primal instinctive impulses. You prefer the real thing because yìou're programmed to procreate. Just the same way that you find the act pleasurable to begin with because you are programmed to.
The idea that not wanting to have sex with a trans woman is 'bigotry when the whole thing is an illusion created by the brain and makes very little sense outside of it, seems a little absurd.
