I agree with your points, but i think it has to do with the fact the women are more emotionally affected by things and have a harder time defending for themselves.
To put it in other words women look for me to take care of them and protect them. its been like this for hundreds of years in society.
this mindset brings us to believe men have more responsiblities out in the real world.
(i.e men in familes have jobs, majority run pf governments are run by men, etc)
Women also are more emotionally affected by little things whereas it seems men are more stolid in affairs when needed be.
because of this things like split custody is unfair for men simply, because it has been the commen thing for the man of a family to take on the real world while women take care of the children and the home. Many courts believe that women will provide children with a better home enviorment compared to men because of things like this. which can be a mistake.
Women in the working world receive more attention, becaue they have va.... they are less common. Women have different ways of getting things done and can be more persuasive and effective in certain areas.
Ah, I forgot that the reason women are expected to take care for the children, be the warm and caring sex, and are under-represented in the workplace and government simply because they are too emotional and just basically unable to take care of themselves!
I am now going to have a little cry over your blatant sexism and then maybe I'll bake a cake or have a kid or something. God knows it's not like I'm going to work now or anything.
