[The Catalyst]

I would imagine:

Violence for no reason is r-selection. Ability to get violent when need be but also ability to control yourself is K-selected alpha masculinity.

Girls generally like the K-selected alpha masculinity but if the girl is sufficiently r she would actually probably prefer a more r(likely inferior) guy. I imagine r girls are really drawn to r guys.

We're missing the main point here. Why does the OP drink whiskey from a cup?

It’s long been said women are much more attracted to men possessing Dark Triad personality traits. (e.g. Machiavellianism, narcissism and psychopathy.)

No doubt that women prefer guys that they think could hold their own in a fight. Seeing a guy win a fight is also probably a big turn on for girls.

4. A charming, violent inmate will leave more descendants to suckle on the state teat than a diligent, law-abiding beta male will leave to contribute to the state teat.

Seeing a guy that is close to death turns women on.

Violent guys are closer to danger and that’s attractive because their seed has an expiration. If she wants the D she knows she has to act fast.

It doesn’t create attraction out of thin air though, just urgency if she already likes you, and perhaps love if she feels you will not last in her life.

It’s a thin line. Times where I had a fit and fights in clubs I lost the girl every time. She’d just freak out and shut down.

Maybe they were too close to the action.

Usually Lowclass girls like violent men. Sometimes they also provoke a situation with other men. When you are with such a girl, you never have peace.
