I think it's a very complicated question that disturb the nation: who can most extravagantly claim to be offended, and proclaim that their feelings and sensitivities have been hurt?
Sometimes, people see rudeness where there isn't any. In these cases they make arguments in favour of political correctness. So for example we could change the names of cities, countries and universities with other words that give no offense because they have no meaning. So my ultimate objection to PC is that it doesn't actually make sense. What I'm trying to say is that it's better to be effective rather than be right. PC is obsessed with how right it is all the time without thinking of how effective it might be.
For example, anyone can be offended by any word but they are only words, it's the context that counts. It's the intention behind the words that makes them good or bad and it depends on who and how use them. We must acknowledge that we can't be afraid of words speaking up the truth even if they are unpleasant, for example I don't like the use of euphemisms in language. i think it distorts reality but also helps people who are afraid, to face the truths of life.
