FreeBSD's new CoC wouldn't ban a sexist comment like this, because of the odd "oppressed group" language. Hopefully it was just a copy/paste mistake from the Geek Feminism code.
There's no place in a software project for insulting someone's gender, race, religion, sexual orientation, etc. just because it's a more typical one. There are certain toxic community members who use well-intended rules like this a shield while they proceed to insult certain groups or stereotype them.
Better to avoid that type of discussion entirely. It's a software project, not a place to discuss politics or race relations. Hopefully they take a look into this and adopt a more neutral CoC like LLVM's: https://llvm.org/docs/CodeOfConduct.html
