That feminists treat their children differently depending on if they're female or "defective".

Feminists are at war with human nature and biology. I've seen plenty of these monsters say that they've tried to deprive their daughters of pink clothes, princesses, etc. - but that miraculously, their daughters are attracted to those things anyway.

Of course I knew what it was about. It was about how to be a feminist parent to a male child

That's surprising. I actually thought that it would be feminists struggling with 'bringing another white man into the world'. Like that Emily Ratratjowski or whatever its name is.

I just sometimes take conclusions that aren't explicitly written, but are hinted to.

In this case, you're not even being unreasonable. In some other cases, we disagree about what is 'hinted' at.
