It's no accident that the ground rules for debate - reason, agreed facts, nuance, willingness to compromise, a fundamental respect for the opinions of others - are in retreat. Certain state actors, populist politicians and a rag-tag of largely right-wing grifters/chancers have worked to make this happen.
In some way they all benefit when debate moves from a battle of ideas to a battle of personalities - it's not what someone says, but who says it that counts. Anyone who doesn't agree with their "narrative" is decried as an elitist who lacks "common sense" or opposes the "will of the people".
This is how people end up supporting ideas that harm their own interests or, to outside observers, are clearly illogical. We seem to be entering an age that is the opposite of the enlightenment - which seems incredible when it is science, and policies that flow from that, which will see us through the current pandemic.
