I'd not react if someone used "fuck" as an expletive (depending on situation), but if someone called another in the discussion for "fucker", or similar.
In sum: A curse is not high class, but might pass. A general insult to someone, because they disagreed, is much worse.
(And I partly agree with the poster, if someone disagrees I'd like a motivated comment. A vote up/down is just frustrating; what can I learn? [Edit: But to vote up/down to show you're (dis)agreeing is the culture on HN, it seems. So I accept that.])
Disclaimer: I'm not a native English speaker, but afaik "cunt" is quite offensive.
