Well, all of it, really, by definition.
There's paranoia cutting every which way these days.
It's my impression that excessive demonization cuts every which way here. We are all human, fallible, vulnerable and defensive about ourselves, and suspicious of others who may not deserve it or only partially deserve it.
Not to say there aren't real bad actors out there. Obviously there are. But there are costs to false positives and false negatives alike.
(No place for this on P3, but I need it on the web somewhere.)
