Common sense is a thought terminator. It’s just “everyone who’s smart agrees with this”. It’s common sense you shouldn’t inject any aspect of a disease causing pathogen into people. It’s common sense that you can’t burn so much stuff you make the whole sky smoky or permanently warm the planet. It’s common sense that you don’t share an ancestor with an oak tree. Now none of that is true. You should get vaccines, uncontrolled combustion creates smog and contributes to global warming, and all eukaryotic organisms share a common ancestor. But if you phrase things right and say it’s obvious people will agree with your false statements and think people are over educated idiots for being right.
