Pascal's Wager and the most optimistic version of the Simulation Argument, where God does exist, and is sifting the wheat (those who get literal eternal joy) from the chaff (example: TWAW belief, perhaps)
"Pascal's Wager" doesn't work for a multitude of reasons, including that cognitively honest people don't choose their honestly held beliefs based on what rewards they'll get for so believing.
Also pretty sure an omnipotent omnibenevolent God wouldn't have needed to create people with gender dysphoria in the first place.
Most likely probability: your God doesn't exist. There also exists a possibility of course (though a tiny one) that he created the trans people you find so appalling to test you (yes, you personally) about how you'll treat them, and you're currently treating them appallingly, with sneering contempt, in which case he'll condemn you to hell or something.
I oppose you being condemned to hell, btw. That's also morally appalling.
edit: whoops, I misread, but no, I have the *ability*, but I do not gawk, I'm not gay, I'm disgusted by other men's penii.
not at all, let's create a third transwomens' shower room, and a fourth one for the transmen, why not?
hurt feelings? too expensive?
Yeah, see, I'm more generally appalled by all the American scenes in American shows/films where people seemingly have to shower communally or whatever. In my country, even when I was in the army for my 1-year mandatory conscription, there were separate cubicles in the showers. You didn't have to get completely naked in anyone else's presence.
Your fear "oh no trans people can gawk other people in the showers" is to me *weird* -- it implies that it's somehow okay for ANY people to gawk ANY other people in the showers, as long as they're the same gender.
Make individual cubicles in your showers. And then you won't have to look at either people's vaginas or penises, regardless of whether they're cis or trans.
Or go the other direction and just decide that nudity isn't a taboo anymore. Creating separate rooms for more categories doesn't work. Trying to fit everyone into *two* categories doesn't work. There'll be eventually people with multiple penis, vaginas and tentacles.
what the mentally ill want doesn't matter: TRUTH is not necessarily KIND, ask Plato about that
So close to the truth and so far away. It's exactly because TRUTH and GOODNESS are two separate things, that the mere facts of the universe (there's XX chromosome, there's XY chromosome, there are people born with vaginas, there are people born with penises) don't need constrain how we choose to deal with other people.
People who say "Trans women are women" don't disagree with you on the facts about whether these people have XX or XY chromosomes -- they're instead saying you should treat trans women like you should treat non-trans women. (I hate the stupid confusion between IS and SHOULD. I try to avoid the IS word because it leads to so much confusion, when people mean SHOULD. But that's a LINGUISTIC issue caused by people who don't communicate clearly)
ALL categories, ALL words, including words like "man" and "woman" are social categories.
You are correct that there are facts of the matter: That person has a penis, that person has a vagina, that person has XX chromosomes, that person has XY chromosomes. What categories human society derives from them however, and how human society deal with those categories in separate situations is a human society concern, not a Truth of the universe.
You can for example make it a rule to have a shower for people who phenotypically look male, and a shower for phenotypically look female. That would means that trans men & trans women will be joining those showers only after they've done surgery/been in hormones/etc.
If you say something that everyone with XY chromosomes is a man -- then well, I've heard the rumor that Jamie Lee Curtis actually has an XY chromosome though she's externally looking like a woman and been considered a woman all her life because of a medical condition.
In that case would you force Jamie Lee Curties to shower with the men, just because she has an XY chromosome?
