1) The discrepancy is between doing something to one's face who's involved in the community and therefore open for ribbing vs. doing something behind one's back who is in no way part of the community and therefore not open for ribbing. If you don't see this difference, then you're fucking stupid. I'm sure the racial comment wasn't meant any more than your comment was.
2) I was intentionally inflammatory and over the top because 1) that's what I expect of you, especially with your hatred of "those dang libs", and 2) because I think you're stupid, not because I'm trying to make a point.
