There should be a whole new layer of Snopes-like debunking, that focuses on newer stuff, like derailing, whatabouting, the unexplained level of examination and point-by-point responsiveness demanded when people don't want to accept something as true, etc. The extent to which claims are made without building up a clear underlying context.
There's a whole new taxonomy of trolling/disinfo, it's not just about logical falacies or fact checking one-off claims anymore.
