Here's a comment I saw elsewhere that I think is a good response to your post.  I hate to say it but you're just rambling on about your feelings rather than facts.

"Well, I've never seen anybody suggest why "systemic sexism" has been so massively successful in keeping the supposed hordes of "qualified women coders" out of programming, but failed so miserably in keeping them out of sales, marketing, law, medicine, journalism, finance, government and education. Especially when you factor in the fact that anything that even vaguely looks like systemic sexism gets you fired and blackballed immediately with no warning or review and we've been bending over backwards to put anti-systemic-sexism programs in place for at least thirty years, the power of the systemic sexism in tech is really a wonder to behold."
