If you don't like mvscal's comments, fine. Needless to say, you're entitled to think he's a moron and jerk -- I admittedly missed the deleted comments, so I didn't have the full picture, but that still doesn't justify what I thought was an over-the-top racial insult. Your mileage may vary.
As for what type of retaliatory action is warranted, I don't know what is being suggested here. My retaliatory action consisted of this -- I simply told Pelham what I thought of his comment. You are entitled to tell me that you disagree with my comment, as you have done.
