I think you should learn to deal with it.OP wrote:snip
Really.
What is or isn't "offensive" is entirely subjective.
I don't get offended when someone swears at me. Or calls me names. Or insults some aspect of my play.
I honestly find it more offensive when someone tries to force their values on me (like when someone tells me it's not OK to do something!) or when someone acts like their shit doesn't stink (I honestly think "sheep me" is more offensive than "fuck you". At least with "fuck you" I know the person is just expressing anger at me in the most blatant of ways, but when someone says "sheep me" it's basically an extremely condescending way of saying, "you have no idea what you're doing and my reads are better than yours, so if you have any sense you'll stop thinking you are right and listen to me instead" but in a oh-i'm-not-being-offensive-here!! cheeky way - it's like people who uses asterisks or "the f word" instead of just saying "fuck" - we all know what you're really saying, nobody is less offended by it because you weren't being explicit).
Look. You have your own set of values, and they're different from mine, and whatever, that's cool for you. But really, I don't give a shit about them, so if there are specific rules preventing it or I'm asked by a mod to stop doing what I'm doing, I will, but I'm not going to take your ideas seriously. Why are your values better than mine? Why should I care what someone else finds offensive if they don't care about what I think is more offensive?
I dare you to find an objective way to draw the line at what is or isn't OK in a game without using your personal values. Or just learn to deal with it if a mod doesn't intervene.
