Keep in mind that I didn't say to ignore them entirely, I said that replying directly is a bad approach.

But bad rhetoric can be countered and refuted without direct attribution. You could instead reply to a screenshot with the handle cut out or just speak on the topic without bringing up who is stirring shit this time around.
