I just had to zap two comments. If you call another commenter, or a poster, a moron, your comment will be deleted regardless of its other content. Same for other insults. Ditto if you use a bad word that might get us filtered out by some electronic nanny. If you do it twice, your account will be banned.
We all value the diversity of the RBC comments section. But that’s a reason to be on your best manners. Do as I say, not as I do: try to disagree without being disagreeable.
