The warning was quoted from the source, so your beef is with The Guardian.

MetaFilter has no shortage of strong language and it's not against any kind of community guideline if it's not being used in an intentionally shitty way; as a moderation staff we've pretty clearly set those expectations straight on the rare occasions that someone has complained about sensibility-offending surfeit of fucks and shits and damns in this or that conversation. I mostly just expect it to be done with a degree of skill and thought.

The exception there is slurs and the like; there's strong language and then there's racist/misogynist/homophobic/etc epithets, and the latter subclass is a different beast entirely that in specific discussions of language can bear mention rather than use when the distinction is clear. But that sort of thing otherwise can, indeed, fuck right off.
