The last 20-years men have been in majority as well. I have no idea why men did this to themselves.
They are liberals before they are men.
I have no idea why almost all women take full advantage of the court system to absolutely screw men, taking all they have to include the kids.
The "men" you speak of that passed all these laws are politicians are were trying to be politically correct and not be demonized by any number of powerful women's advocacy groups. The media is certainly a women's advocacy group.
How many advocacy groups do men have? None that I can think of.
