Be kind. Don’t be snarky. Comments should get more thoughtful and substantive, not less, as a topic gets more divisive. Have curious conversation; don’t cross-examine.
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 respond to the strongest plausible interpretation of what someone says, not a weaker one that’s easier to criticize. Assume good faith.
