Yes, I'm sorry for being incendiary. However, I think shame and guilt are excellent tools for getting a culture on track. Better than war, anyway.

If you continue to post slurs, we're going to have to ban you. I don't want to ban you, but you can't do this here. Please don't do it again.
One of my teachers once told me "I did a Ph.D. in psychology at Stanford and I learned just one thing from it: that punishment is not good for learning." Hopefully we can get to a state where there's less punishment and more learning. I think examples are good for learning, so I hope you can stop feeling guilty and just take it as an example.
