Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."

Please don't fulminate. Please don't sneer, including at the rest of the community.

Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.

Eschew flamebait. Avoid generic tangents. Omit internet tropes.

Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.
