"I want to burn a fag after breakfast"
This will surely upset someone. I can almost promise you that they will not be from the UK. Should we ban whoever said it because they used the word "Fag". I don't think so. However, let me be clear, we are still perfectly in the right to ask them not to use it. Hell, infract them, but don't ban them flat out. There is a middleground here and we should use it, damnit!
