I've noticed that they blame everything on the so-called "patriarchy" to avoid accountability. The entire argument seems like a smokescreen—they're simply looking for anything to shift the blame.
Just think of how people from a primitive tribe might look upon you: "What? You're a man who failed to copulate with a woman? Are you not even able to attract a single woman? Haha, you're a failed man, you're pathetic!" This is a natural state. The stigma doesn't "come from the patriarchy" or something absurd as that. It's a natural state of mind.
Also, telling incels that "patriarchy" is the reason they want a girlfriend is completely missing the point. Incels don’t want a girlfriend because of social pressure; they want one because they’re lonely and desire intimacy like everyone else.
