Yet they are allowed to drive cars, fly planes, raise children, buy guns and vote but somehow cannot decide for themselves what’s good or bad, and need a higher moral entity like Facebook to babysit them. I find this a weak argument.
I don't know what a way to show that you are a rational, well informed, mentally fit citizen able to responsibly vote without falling for basic fakes news and misinformation attacks would be.
At least denial of reality should raise serious questions. How can we expect a flat earther, 6000year-old-world believer, climate change and holocaust denier to rationally chose who to put at the helm of a country?
Politics should be about people disagreeing on the means to address a set of common challenges, not about those who imagine living in another world so far removed from ours that they can't have a valuable opinion.
