So many factors are involved.
1) Might be how they were raised. I always remember a clergy once telling me: "give him/her to me till they are 5 and they are mine in mentality for life".
2) Some men just are wired that way I feel. AS an example, I was raised that women belong in the kitchen and keeping the man of the house happy. Maybe that is a small reason why my "dad" hated me to his core, as I have always felt that we are ALL the same and a million minds make a whole, as far as everyone has something to contribute, NO huge egos please are my thoughts.
3) I hope, never in my lifetime at 68, but someday, whereas we evolve (hopefully) we learn to not only respect each other, like the old saying "would I like it done to me?" but also take into account of wasted opportunities, as when men and also women sometimes, it can work both ways, as a post I did a few days ago, where one time a gal would not go out with me unless she got sex on the date, talk about pressured and against my beliefs.
You brought up a very interesting angle/aspect of human nature that to me is just downright a negative, treat everyone the way you want to be treated period, enough said.
Have a great day everyone!
