Sexism is a fun topic to discuss
Gender roles in the past (just a few hundred years ago) were incredibly rigid. They were born from a culture informed by religious dogma on who does what
men work the fields, butcher animals, chop wood, work leather - do hard physical stuff
women cooked, made clothes, cared for children (and popped them out...) and occationally even cleaned
then the industrial revolution came and the old man-jobs were industrialized. combine harvesters replaced men in the fields, meat packing plants and assembly-line butchering made small-scale farming unnecesary, cutting down trees and chopping wood was replaced by coal mining and leatherworking as well since people now just bought shoes.
in turn men started working in the very same factories that made all that stuff. fun
women on the other hand still largely stayed at home. But with the advent of industrial fabric production, with automated looms, you could buy cloth by the bolt! So women had to make more clothes! actual industrial clothes-making is a later invention. Oh and look at the running water, and electricity! Now the woman has to clean and vacuum and wash all the bloody time! Oh and industrial flour production means that the old home-milled rough flour is now all fine powdery fancy flour! Time to bake a shitload more fancy bread!
basically, while the male workload remained the same - the female workload of the archetypical housewife has actually gone up... sure, its kinda equalized now (kinda) but the cultural stigma are still there
look at childrens toys. girls play with dolls that engender mother instincts, while toys for boys are far more rough and tumble. What gender roles are you taught there?
I for support the idea of gentlemanly behavior. I don't see anything wrong with it. The trick is to be conscious about the signals of what you do.
Equal rights? Certainly! But when I hear about lobbyists advocating affirmative-action like laws to force women into boardrooms? No. For while I'm sure there are a lot of fatcats and whatnots in boardrooms, and that some do treat boardrooms like an all-mens clubs, then making the gender of a boardroom member and not that person's qualifications the deciding factor... No.
