At the time it was happening I recall thinking "This should be a typical flair up that'll die down to smolders in a couple of weeks and life will continue" as so many dicey internet things had done in the past but that time there was something that kept that fire burning, it wasn't organic feeling, it was as if it was hooked up to life support just to stoke more engagement and stronger, more subtlety incompatible opinions.

It worked, we collectively fell for it hook, line, and sinker. It keeps working. It will likely keep working for a long time as people continue to feel empowered by self-entrenchment and the want for affirmation that they're on the right side of history.
