According to cucktears, every single incel ever.
In a way, they're right. Because incels are nothing but a group of loser, ugly, low-status males that, instead of doing what modern society expects them to do (rotting nice and silent on our littler corners and/or being weak whiteknight/male feminist cucks), dare to scream "I'm here, I'm a man, I have sexual and romantic needs, I won't take this shit".
There's a strong element of self-assertion and self-interest in that indeed, which could be linked to narcissism somewhat.
I said it numerous times and will say it again, the difference between an incel here and an ugly, low-status whiteknight faggot on Reddit is just pride/honor/self-assertion.
