Don't understand it as a rational thing, understand the hate as a cancer with its growth being juiced and accelerated by the ruling class because incels are the easiest demographic to scam into violently acting against their own interests.

A cancerous process is by definition irrational from the perspective of the body it acts upon, the reason the cancer exists and grows is not because of a motive, desire or need but rather because the cancerous process consumes all the space and oxygen in a room at a faster rate than anything else can compete with while remaining invisible to the body as a threat.

Toxicity towards women displaces other topics and viewpoints specifically because the men pushing those topics want to monopolize the discussion and framing and often centrist types don't challenge that at all because of some self-perceived high ground to tolerating intolerance (not something you tend to believe in if you have experienced serious hate).
