Here's the deal on the Pup, from where I sit. If, over the years on the internet, you simply can't or won't restrain yourself over and over and over and over and over again from referring to the "neeggers" in the most crudely derisive terms possible, then, guess what, you're probably a bigot racist in a significant part of your heart no matter what else you are.
Crude racism. I don't much cotton to it.
