Man of Harveys said:Depends how "free" you want to be - this so-called "harm principle" has been debated by moral philosophers a lot cleverer than me since at least the days of John Stuart Mill and will be again. You and I and everyone else operate in a society. You do basically have the choice to ignore the norms of that society, i.e. to act according to your free will. But most of us would agree with ol' JSM that some regulation in order to protect the liberty and prevent harm to others is no bad thing either - he was a compete libertarian (I think he even coined the term) but even he made out a case that some things were harmful.
So, in this context, maybe the most important thing is to consider the harm done. Shouting "Oi, get me a BLACK coffee NOW, hur hur" might be harmful if it's obvious you're trying to be harmful with that remark.
However, the moral dilemma with which I (honestly) flirted when I once had to ask a black female barmaid for one of my favourite whiskies - Black Bush - was an easy one: she knew I was asking for a drink rather than talking about her no-doubt lovely fanny.
MOH, I often do not agree with your posts, but there is a lot of sense in that one, followed by the funniest thing I have ever 'heard' you say!
