A dismissal or lack of consideration for the unique issues facing men and boys and the unique solutions they require. Focusing exclusively on women and girls. Viewing boys as defective girls.

In this thread, here's a few specific examples

Let’s use their own “reports” to show those women that their boyfriends/husbands/fathers think they own them.

The rate of girls identitying as liberal is significantly higher[...]Probably because the girls face actual threats to their freedoms, while the conservative boys’ complaints are about a bunch of imaginary nonsense.

I was a “Fox News”-viewing turd in high school, too[...]then I grew up.

It's passive because it's not direct and focused. It's more neglect than abuse. Men's problems are not just secondary; they're not even worth consideration, and men should just Fix It Themselves.

Schools in particular are extremely geared towards focusing on girls and their successful development.
