These aren't just whatever, "it's just people making choices". It's clearly social and political influence.
you also shouldn't care about us people trying to effect social and political changes.
We're not supposed to care about your deliberate interference, but you're allowed to care about the choices women make, because society got in their heads and made them make the wrong choices?
Normally I don't care. But people like you are not trying to eliminate the sexism (probably because your assertions of it are vastly overstated), but trying to change the nature of the field to make it more friendly to stereotypes about women, without any consideration as to whether these changes will actually improve the field and the skillset of CS graduates.
Read this article about one presumably successful effort.
And let's look at the assumptions these efforts make, and their solutions.
"The first class you take is a weed-out class, and they are shocked by the fact they don't get any women at the end."
CS is too hard for women because, despite growing up with computers, they never learned how to program before. Lighten the intro courses to be less "weed out".
"Know-it-alls in any section are told to cool it so no one is intimidated."
Women are intimidated by knowledge and enthusiasm. Don't show off. It's too... manly.
"Along with changes to the introductory courses, Mudd works hard to keep women interested in the field."
Women need to be pandered to to keep them interested.
"Women and men work through problems in very different ways"
Women's brains are different. But still, ignore those troglodytes who said women are naturally less inclined to be interested in abstract machines.
"They bemoaned middle and high school math teachers who didn't engage or inspire."
More pandering is the solution. Nevermind the boys who never got that encouragement either. (High school CS curriculum was a joke twenty years ago, and it still is.)
Is coddling women going to make them better programmers? Who knows, maybe it will. But don't pretend you aren't coddling them.
