Good.
Better they fester in silence in a place where they can be observed and reported to authorities when they cross the line. Without a popular, legitimate, high traffic platform that allows them to influence a mass audience the cancer doesn't metastasize.
I can't banter my own mother into giving up whatever conspiracy theory crosses her path. There are so many people with equally poor fact-checking and critical thinking skills that they form their own festering bubbles on popular platforms. The bigger the bubbles, the more extreme they get, and now the end result is a confederacy of deluded, violent extremists sacking the capitol. We're lucky it wasn't worse, but this might be a dress rehearsal for far more violence if we don't get a better grip.
