Your comment pointed directly to race war. That's practically the biggest flamebait there is—especially when you use high-indignation, low-information phrases like "how much you discriminate against $group".

It's important to understand the concept of "generic tangent" - when a thread moves away from the specifics of a given story toward more familiar/bigger/hotter/divisive/sensational things, the discussion is guaranteed to get more repetitive, less interesting, and more likely to turn into a flamewar.

You can't judge these things by upvotes—sensational comments and flamewar comments frequently get heavily upvoted. This is a weakness of the upvoting system. Past explanations here: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so....
