As for your statement that some people seem to have a need to be offended, I can turn that around quite easily. People who offend sometimes have a deep, inner need to hurt other people as a means of disguising their own inadequacies. Unfortunately, in this case, it only serves to fulfill a personal service rather than a public one. Not in all cases, mind you. In some cases people simply do not realize that what they say hurts.
Many people can shrug off and ignore racial slurs.
It hurts, but they can shrug it off. To them it really hurts. Unless that's the whole point. Could also be you are just trolling. I do not have the need or desire to insult you.
