Also the statements that people “worry might be believed” may not intersect with the statements that could be judged as plausible by an intelligent, rational person. There are a loooooot of dumb people out there, with uncomfortable levels of individual and/or collective power. When that cohort falls for something that smarter people see as blatantly false, it still can have nasty consequences. We should be angry at anyone who deliberately attempts to make them fall for it.
