If I've offended.

People use the phrase "I am offended by that!" and expect it gives them higher ground, moral authority, or some sort of license. No. What it means is that you are offended.
So fucking what. [This is a paraphrase of something Stephen Fry just said on the radio.]
I once offended an ex GF by putting on after shave. It turned into a big fight about my underlying passive-aggressive motives. (ex indeed!) The same is true of language. I think political correctness and censorship are the small minded neurotically trying to enforce and prop up their own world order. To that end, I will make every effort to only say what I mean and own it. That way we'll know where we stand with each other...cocksucker!
