So, the idea is that being nice and kind to women DOES NOT get you sex or close to sex or even factor into that calculus.

Cool, fine.

But...

...what's the remaining incentive for men to treat women nicely, then?

If it's all about attraction and that's amoral, then........

....once a woman is attracted, what is the point of being nice?

Don't come at me with the 'to just be a decent person' angle because...please, lettuce be cereal. Kindness is effort and effort without reward is wasted energy.

Look at it evolutionarily. If it doesn't result in more lays and kids, it kinda disappears from the population --- even if it isn't genetic, it's likely mostly heritable in the sense that environments (teaching about how men treat women from parents as role models) tend to also run in families (poor parents tend to have poor kids).

So what's the incentive to treat women well for men?
