I'm sorry you went through that. I was raised by a feminist mom and with two older sisters, but they never went that far. So I sympathize, and would buy you a beer and a cigar just for those. Eventually you have to forgive people, including your mom, for doing stuff they couldn't possibly understand. And move on. You're already moving on, so keep going. If you're mom hasn't learned yet, just move on in your own path without her help. If you can help her learn, then do it, but be yourself first and foremost.
