Please don't take HN threads further into generic ideological flamewar. It leads to tedious, repetitive, and usually nasty discussions—see first reply below.
One thing to look for is whether a comment remains anchored in the specific content of an article, or has become unmoored from it. Most of this thread retains at least some contact with it. Even the parent of the comment I replied to (https://news.ycombinator.com/item?id=21866584), which is pretty generic, has at least a wispy string connecting it to the OP. But https://news.ycombinator.com/item?id=21867096 just goes into talking points.
