Gotta love a three-hour old account trying to convince people that police racism and violence isn't real. Are we twitter now @dang? The astroturfing hasn't been subtle lately.
The guidelines specifically ask you not to feed egregious comments by replying (a.k.a. please don't feed the trolls), but to flag them instead. Other users did that, and so the GP comment was rightly flagkilled. If you had done that instead, that would have happened sooner.
If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and sticking to the rules when posting here, we'd be grateful.
(Edit: Fortunately your comment history seems just fine for HN so this isn't a longstanding problem.)
I understand that for controversial topics many people have deeply held beliefs and so experience a strong emotional reaction if they are questioned. It is easier to dismiss someone as a "troll" rather than examining why they hold these beliefs.
This was admittedly my lowest quality comment, but it is hard to see what was objectionable about the previous three comments, which were almost instantly flagged. The statistical evidence points to a very small role for racial bias in explaining differences in the use of deadly force by the police. What's wrong with pointing that out when it is directly relevant to the discussion?
