Good point, I would be interested in learning more about that. I feel like it may be because the insult is always a precursor to their actual message. For example “you’re a loser with no girlfriend, but it’s because women only respect alpha males. Here’s how you become one…” It uses their insecurity to sell them misogyny and right wing ideology. I think structurally different to and mentally easier to accept than how a man might be insulted from a left wing perspective. Example: “you’re a loser with no girlfriend because you’re an incel who hates women.”

Objectively the left wing one is closer to the truth and heeding its advice would be more likely to socialise them and put them on the path of finding love and companionship, but it’s pretty obvious to see which of the two a young inexperienced and insecure man would be more likely to follow.
