Facts don’t matter when an influencer commands an online mob. This has been true for years now. There is no counter-speech from outsiders that will be taken seriously or trusted. The targets of lies aren’t asked for their side, and wouldn’t be believed anyway, so there’s little incentive to participate (and legitimize the “controversy”). There is no 3rd party fact-check that will be carefully evaluated on its merits.
This is really the only dynamic that matters in our politics today.
