Death threats and actual harassment are serious business and are a matter for law enforcement, but a great strategy for dealing with the casual climate denier, anti-vaxxer, or Q idiot, is to just laugh at them. Not with, at. They cling to these ridiculous theories because at some level they want to feel in control and relevant in a scary world that they either won’t or can’t understand.
Treating them like kooks and refusing to get aggravated hits them the hardest because it tickles that suspicion that they really don’t get it. On the other hand, getting frustrated and trying to debate them about whether Hillary eats children just fuels the internal narrative that they are heroic truth warriors holding out in a hostile world.
Either way, kooks are gonna kook. You are not going to change their mind anyway, so why let it destroy your mental health.
Looking at comments on the bird site, I am pleasantly surprised at the number of submersible experts who are also Kremlinologists.
