I was a bit unfocused, but I meant my comment to suggest that what you perceive as this community having a number of "loud trolls" may be overblown. I have been on HN for many years and the number of times I've seen a comment I considered intentionally hurtful (dressed up or otherwise) is vanishingly small.
To put it another way: you say that people who are merely politely disagreeing are in your category 1, but you also believe there is a problem on HN with "loud trolls" dressing up their comments to appear civil. That's counter to my experience here. YMMV etc of course.
