The desire and even need for, sure. The feeling of entitlement to receive it, not so much. That’s not healthy.
There is no typical incel, no archetype or particular backstory. It is not just anyone who finds themselves rejected by the world, it is only those who blame the world and wish to harm it in return.
Is the Joker an incel? I can see an argument either way, but I’d say so. Would incels identify with the Joker, as described by those defending him in this thread? Yes, absolutly.
Now, does that mean that they go out and they commit terrorist acts? No, they probably don’t. Does it mean that our stochastic chances of violence from that segment of society is increased, I’d say, yeah, most likely, by a tiny amount, but that’s not what I am worried about.
But, does it mean that some socially isolated people find validation in their feelings of alienation, and justify and rationalize their choice to withdrawal further from a world that doesn’t play by the rules they deem to be fair? Yes, I think so.
Violence can be cathartic (even though it almost never actually is), and seeing violence even fictional violence perpetuated by those who deserve it for living in a world that would treat the protagonist in such an unfair way can make someone who feels treated unfairly feel better about themselves, but not in a healthy way.
Take the movie John Q., we are meant to identify with a hostage taker and a terrorist, on the grounds that the world is being unfair to him, and his actions are justified. If you have seen this movie you cannot not identify with the father doing anything to save his son.
So, are we supposed to identify with the protagonist of “The Joker”, or condemn him entirely?
