This article is completely correct of course. But there is zero hope that it'll be taken seriously at all.
Just the other day, here on HN someone seriously proposed the idea that hate speech doesn't lead to violence against minorities[1]. I pointed at the Rwanda genocide, and got voted down (a lot), because the OP claimed that 10% of deaths didn't prove my point. Then I pointed out that was at least 60,000 deaths, and that was downvoted too.
Enough people clearly want to ignore things which disagree with their world view that there is zero chance that this destabilising behaviour will stop.
I was simply justifying my downvote.
