Tonnes, but I don't see your point. If people wanted to put some context on words and phrases I use that'd be fine.
The point is that we must use loads of words all the time that can be presented as offensive to someone. I couldn't give a fuck about that, I only care about the context. I ask "what does the person mean when he says a word, and why is he saying it?", rather than "what did that word mean 100 years ago, and why doesn't he know the historical context?".
