Furthermore, consider that the opinion-like discourse is clearly performative. We all know what the correct virtue signaling looks like, and we know that we need to ruin every person not doing the correct virtue signaling.
So it's less of a plurality-of-opinion situation, and more of a direct-democracy situation: a lynch mob.
(Not saying it's good or bad btw -- not my circus, not my monkeys. Just dishonest to say we love some sort of plurality while doing this I think.)
