Not really sure what point you're trying to make.
At first it reads like "Lots of men deal with loneliness and keep it to themselves, which creates a vulnerability that nefarious actors exploit." The logical conclusion is that men forming an ad hoc support group on a thread joking about dying alone is actually a healthy thing because it minimizes the attack surface and gives men a place to vent without being exploited, gives them a place to find emotional support without being demeaned or self-effacing.
But then I'm not sure if the second half of your comment veers into "the men gathered here are all incels and actually it's okay to beat them while they're down because they're easy targets and aren't worthy of basic respect" or if you're saying "actually incels are something different from what you see here, and these are just normal guys sharing a rare moment of emotional support."
