if you define “incel” as “one who threatens women or worships murderers” then that’s true. Otherwise, I think you have a bit of a “no true scotsman” thing going on.
Again, you’re trying to make it about fairness or who deserves what – which are considerations I’m intentionally putting to one side.
i don’t think sympathy would make any racists less racist, but I do think it help some incels feel less alienated. In other words, I think it might work for incels but not for racists. That’s the difference.
Assuming it works: because it works. Assuming it doesn’t: there is no reason to.
Yes, so they probably do not deserve any sympathy. That is irrelevant to any consideration of whether sympathy works.
“Incel” just means “involuntary celibate” as far as I can tell. It doesn’t seem to me like it’s really an ideology or a worldview but a bunch of alienated young men feeling intensely sorry for themselves. That can lead bad places. If you have any really good ways to prevent that sort of thing, then please share! Otherwise, I’m suggesting that sympathy might possibly help. It also might not! But you don’t know until you try.
So do ours.
