Fact-checking and debunking, as Snopes does, used to be apolitical and fun, as well as educational. People who read the explanations often learned from this.

Nowadays, refuting the spew of right-wing lies is ineffective; right-wing fanatics don't change their minds no matter how much evidence is piled on them.

If someone you know has fallen under the truth-hating spell, then unless you have the best information on how to lead someone out of it, and wish to put a lot of patience and effort into it, I suggest cutting off those conversations rapidly.
