This nation is terminal with a problem. It is really simple, too.
All anyone cares about is 'me,' from their own point of view. If it doesn't effect them, they don't care. And, men are especially guilty of this. To them, sex is just a hour of fun (2 minutes of work, 48 of sleep). If the woman gets pregnant, and it isn't a male, they ignore it in most cases. Some, a rare few, are different.
Sexism is started at birth, for everyone. Blue for boys, pink for girls. From them, well... Some, like gay men, get stuck with 'pink' anyway, which isn't fair either. What is between your legs has nothing to do with your abilities to do things. But, we're not likely to change this for another few eons, I guess.
Some things, I cannot help but agree with. Women in combat, for one. Most men do not get raped when captured, but most women do. Again,men are to blame. Men used to rape men, but most of that has disappeared, as homophobia has spread so. But, other things, are a joke. Women can fight as well as men, maybe more-so due to have only one head that needs blood at any given time. Men, well, they don't do as well in most cases. Plus, women defuse most men, on site. :)
Those of us who do see it, are usually listed as mentally ill, and locked up. If not for that reason, then for some other thing that we notice, that makes us different from other men. And, in most cases, we tend not to be popular with women, as they like abusive men who run them down. I'm still trying to figure that one out, so give me some time. I suspect it is due to bad fathers, and it carries over to bad husbands, as they expect that is how a real man acts. :(
