It's not good.
I have known a few man-hating feminists with sons.
And I feel really, really bad for those boys.
These boys typically cower in fear, dress in gender-neutral or baggy clothes, are forced to eat vegetarian and/or vegan, and don't get outside for much exercise. I've witnessed some extended tongue-lashings from such man-hating feminists toward their 4 or 5 year old sons that basically shame and blame them for even existing. And that was only in public, I could only imagine exchanges in private. It's a sad, sad, sad state of affairs.
