It's quite possible to expresses the strongest disapproval of someone’s views without throwing insults. It's easy enough, for example, to explain why you believe that something they have said has racist implications, or give reasons why you question the sincerity of something they have said.

As for "And your barely-concealed attempt to take the side of someone who apparently is, or has been, your crony, and stoke the fires in your OP, is beneath contempt and unworthy of you, Kevin.
