People on the far left have a lot in common with people on the far right in terms of denying science. I know extremely liberal people who are irrationally terrified of vaccines and pharmaceuticals, and want to live off the grid in the middle of nowhere. The difference is they fantasize about being on a hippie commune homestead where everyone is tripping and singing kumbaya together after dinner, while the far right people fantasize about being on the homestead with their family and a hoard of guns, 15 miles from the closest neighbor. Either way, the same conspiracy theory is being pushed.
