Wasn't she saying that the child-rearing practices were a net good?
No. She said it was what we used to need. Her entire video is about how little we value male life and we indoctrinate males to sacrifice themselves for others.
Edit: Yeah, this is all wrong. See my discussion below.
She NEVER said we should stop that kind of indoctrination. She barely acknowledged it was indoctrination.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
