Ought to be a trigger warning for that one. ;-)
I was bullied in elementary school which gave me a high sensitivity to social rejection. I was really afraid of dying alone in high school. Although I was not treated cruelly as a teen I heard a lot of "be yourself", "be a decent person", "it will get better in the sweet bye and bye".
That was the beginning of seven years of despair which still affect me decades later. In particular, a lot of guys seem to focus on "being a decent person" and find that what they get is a lot of listening to women complain about their bad boyfriends. (I didn't particularly fall for that --it but I have a tenant who tells me all sorts of things that women told him that he shouldn't be repeating to me.)
I think a lot of men are in situations where they see no path forward. The blackpill incel stuff is poison but I know I felt absolutely alone (couldn't get any recognition from adults and teens that I had a problem) when I was a teenager and if Wheat Waffles had been around back then I probably would have thought "here is a movement of people like me, for the first time I feel like somebody hears me"
(My son had a friend fall under Wheat's spell and he disconnected from my son Scientology-style because my son was taller than him and was concerned my son would "heightmog" him.)
Listen or not you're going to hear more and more from people who steal the vocabulary and discursive techniques of the incels.
If people pay attention they might discover the magic keys to solving problems like "blacks vs the police", "residential segregation of racial minorities", "women getting paid less than men" and "i can't afford healthcare" that never go away -- all of them have a structure similar to the incel problem in that people are making a demand which could seem reasonable in the abstract that becomes unreasonable or unsatisfiable when you expect that some particular person in some particular situation do something for you.
