“We’re talking about people who are mentally ill and liable to kill themselves if their fantasies aren’t indulged. Issurim of lo yilbash, mesares, etc, are chamur, but not yehereg velo yaavor, so the poskim allow it for pikuach nefesh.”
I can’t tell if you’re actually being serious or getting this thread back on theme. There is no way threat of suicide can be used as a real heter. This would be the omni-heter. Example:
Shailah: I’m addicted to posting on the CR and doing other things on my computer, so Shabbos is really boring and depressing. Can I just stop being shomer shabbos?
YCT Teshuvah: Well, if it would help your quality of life, then yes. A poor quality of life can lead to suicide, therefore it’s a matter of pikuach nefesh.
It’s also medically misguided and seems to be taking pointers from leftist activists who frankly make up most of the medical field. Indulging a mental illness does not make it go away. That’s like saying the cure to alcoholism is more alcohol. These people commit suicide because they’re insane, not because “society” doesn’t play their little game.
