It's easier that way. If they're demonized, it means we don't have to grapple with the deeper issues and try to find some sort of solution to these issues. They're incels, thus (according to mainstream thought) they aren't deserving of empathy or help. They're sexists, racists and alt-right scumbags. Who cares if they die alone? Sympathize with them and you're lumped in with them too.

It's not surprising, considering how difficult the topics are that are at the base of these issues, but it's still depressing. We're no closer to bridging the gap between the genders than we were 40 years ago, and it seems to be getting worse in different ways.
