Well this was in a way kind of a response to you as well. Perhaps not your specific case. Yet I think your case would be encompassed by this.
I've been annoyed by the words you referenced many times because, I knew I was not supposed to use them and they could. Yet it seems okay for them to call me Cracker and other terms. SEE-SAW effect.
Yes I think in an ideal world those terms would never exist. Maybe over time they can can be erraticated, but I think there will always be some exclusivity among groups of people.
But I am glad your posts are getting the rewards I feel they deserve. Between your comments and blog posts and poems you really do a great job tackling many different types of content and I think both of us see the value in commenting with meaningful posts
