Most bigotries are based in nothing, but gender discrimination is one of the most insidious because it's based in something (that comedians and gender science researchers* have noticed for centuries):
men and women are different.
A person of one color is not genetically different than a person of another.
A religious person could have been born into a family with a different religion.
A person of one ethnic background could have had a different cultural upbringing if born elsewhere.
Someone from Krypton could easily be raised with an Earthling value system**, after crash-landing in fictional Kansas as a baby.
But women are discriminated against on Earth AND Krypton.
You can't escape it, even with a spaceship.
(Evidence: Superman's female counterpart is not Superwoman.
She is Supergirl.
She can punch a hole in your chest, but her powers are super girly, and the hole she punches will probably be pink around the edges. Also she likes shopping.)
So that's why misogyny is here to stay.
Though it might undergo a name change at some point, if women are detested enough to get the word "Miss" out of the word for hatred of them.
e.g. "Miss Ogyny? I don't think so. It's Mister Ogyny from now on."
Quick last point: one might rightly point out that homophobia is another bigotry that is based in something, probably the exact same something that misogyny stems from: the idea that to be feminine is inferior and that all female behaviors are weak and undesirable (including the liking of men).
Which explains why lesbians are more acceptable (because they at least are attracted to the right gender, whereas women and gay men are wrong because they like men).
It seems the only solution would be for Krypton's gay neighbor planet to explode, and for a bunch of spaceships carrying super-powered homosexuals to crash land here.
Then we'll see some progress on this bigotry front.
Oh, also spaceships full of more super women. That would help as well.
Almost forgot we were talking about women.
Even quicker, even laster point: one might also point out that discrimination against the elderly has a real basis as well. But who cares about the elderly, right?
(Answer: no one, until later.)
So perhaps this is, in fact, the most insidious form of bigotry, because it eventually affects even its own perpetrators.
Unless the perpetrators are so committed to their cause that they kill themselves before elderliness sets in.
That's hatred. Or social progress.
(If bigots only killed themselves instead of others? What a world it would be.)
Quickest, lastest point: bigotry is complicated.
I shouldn't have attempted to take it all on in one fell blog swoop.
Stay tuned for more.
