Nah, I don't agree. I don't see how the US is special in this regard, yet anti-vaxers, flat earthers, fundies, conspiracy nutjobs, sovereign citizens, and every other flavor of anti-intellectual crank are a distinctly US phenomenon.
And what's worse, like an infectious person, we're sending out that corruption into other countries. We're actively funding and sending people to stoke homophobia in Africa, our idiots are indoctrinating others online to work against their own interests.
