They're not talking about swearing. Call someone a fucking shit-eating worm is fine. But on the other hand are words used to insult marginalized groups (women, homosexuals, the mentally disabled, etc.). B/*itch, wh/*ore, c/*nt; c/*cksucker, f/*g; r/*tard, a/*tist, etc.

These are the words being blocked. Not swears, slurs. You can say fuck, shit, damn, and hell all you want.

For what it's worth, I tend to fall on the side of a little bit being fine. I don't use those words (except the slurs against w/*men), but if there's one thing I fucking hate, it's Scolds. If Felix Biederman wants to call people r/*tards and c/*cksuckers, I think he should be allowed to, and I'm not going to try to cancel him for it.

I hate ml mods as much as the next guy, but also I would consider "bitch" to be kinda misogynistic in certain context.
