You're making my point for me. This is the line that was said about girls 30 years ago. They were not impeded from entering STEM either, but they also weren't encouraged like the boys were at the time. Boys are no longer encouraged or nurtured to do anything by our public schools (STEM or otherwise). The lucky ones have examples in their lives they can model after.
As for the "fate" you're fearmongering about for women, what is that to you? I'm not worried about men staying home to raise children. Hurray for anyone that can do that in this economy. I'm worried about men rotting away on drugs, committing crime, and ending up dead or in prison.
You acknowledge that girls need encouragement but think boys will just "figure it out." It's you who must be trolling.
Girls: You will be an astronaut stem president boss queen with less than $REPLACEMENT_RATE children! Boys: Hey how about be a girl
I wanted to learn more about computers but the staff that were savvy were much more excited about teaching the girls, they rightly figured I'd have no trouble exploring that interest. At the time it was fine if mildly frustrating, now I'd be pretty worried about such behavior.
