I do recall members who doggedly kept drawing conclusions in spite of the facts, because of Faux News opinionators and YouTube pseudoexperts and talk radio spittle machines.
I suspect this is an era where minds will change only when bad policy and bad science lead to hideous catastrophe. It takes a lot to shake the faith of personality cults. As in, the sword of Damocles has to stick you in the head before you wil look up.
But have seen a few members here get a bit more skeptical of some sources. Maybe there is hope.
