Fair enough, then, Sagradafamiliar - I didn't know that!
I don't think we're at odds as to whether somebody has the right to use a word knowingly to offend; of course, that's a terrible thing to do.
I think we might just have to disagree as to whether a word that some people consider archaic whilst others consider an everyday innocent word IS categorically defined as unquestionably archaic and/or loaded and thus considered verboten for everybody.
Not quite the same thing, I know, but back to the different country scenarios, there are some words that are widely considered offensive in one country but as everyday mundane words in another, and I think this is just a British regional/generation/class version of that.
In the USA, the words 'damn' and 'hell' are widely considered offensive and most public figures would steer clear of saying them in public, for fear of offending people. In the UK, nobody would bat an eyelid at them. Then again, I can't imagine a politician or TV presenter (before the watershed) saying the word 'shit', but in the Netherlands, it's a completely mild, everyday word.
Somebody mentioned the word 'slut' upthread. I think Godfrey Bloom got in trouble for using this word a little while ago (not the only thing he's got himself in hot water for!) To most people, it's unquestionably an insulting and sexually shaming word, whereas, for posh people of a certain generation, it simply means 'messy'. Telling the latter that it's an offensive word would just leave them completely puzzled - as puzzled as would be most 'common' people on being told that it isn't an offensive word.
