Words are all we have here. By BoB's logic I can say 'I'd prefer it if you refrained from speaking' and would still get a warning. What I'm trying to say is that different people find different things offensive. F is generally the most offensive to the most people, so why even try to deal with it? If the word 'anyway' offended a great deal of people, I would stop using it here, though it's one I use frequently. The English language is so vast that there will always be a number of ways to fully express yourself. 'Hell' and 'crap' aren't considered as offensive by the majority, so they aren't banned here.
