Why do so many parents (particular mothers) try to brainwash their sons to kiss women’s asses?

You usually see fathers trying to raise their daughters to be tough and careful around men. To certain extent that’s definitely practical and good. But more of then not mother tried to raise her son to be “nice” to women.

This might of made sense back in the 50s back when women actually respected chivalry. But nowadays modern women more often than not see that as weakness and they reject and/or friendzone.

My mother absolutely did this shit to me and was very controlling. I wouldn’t say she dominated my father but more often than not she got her way. It was an unhealthy.

Anyway I am grown man and am way too old to blame them for my problems. But it’s been tough over the years not too feel some deep anger for being brainwashed as a kid to be a “nice guy”.
