I'm drunk so don't expect total coherence.
My hn name is based on the fact my original account got banned for stupid reasons. And once or twice in the years since, I have had an email with dang or a comment thread.
My hill to die on is good faith. I think dang does. I think any system is imperfect, but that he does a good job of changing bias and filtering noise.
To be a bit flippant: i see plenty of right wing chatter i find ludicrous, but it isn't deleted. Which is good, and proves the point. Dissenting views presented with a different message, without insulting users, and said in good faith should never be deleted.
