I see. Yeah, it's a vexing problem. Occasionally I make a comment on HN with the best of intentions, and despite that I'm accused of not discussing in good faith. I haven't found a good way of persuading them otherwise once that happens.

It's frustrating because I think it prevents some really interesting and important conversations, especially on difficult topics.

Yeah, I agree. I have to admit that I've probably been on both sides of that. It's human nature I suppose.
