FWIW, I didn't downvote you, I'm just suggesting reasons why others might have.

> Be kind. Don't be snarky. Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

> 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. Don't introduce flamewar topics unless you have something genuinely new to say. Avoid unrelated controversies and generic tangents.

> Please don't post shallow dismissals, especially of other people's work

> Please don't comment about the voting on comments. It never does any good, and it makes boring reading.
