FreeBSD wouldn't sanction the poster for that comment for several reasons:
1. The CoC committee acts on reports -- someone has to be bothered by it.
2. It isn't an insult.
3. It isn't sexist.
"Unfortunately the [group engaging in negative activity] is also almost entirely comprised of [x]." where x is some immutable or deeply personal characteristic, is advancing an offensive stereotype.
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
