Literally, we have a class in media literacy that tells us on how to look for covid misinfo. Especially on its origins, the spread, and the treatments.
Im too awake for this. Good thing I have a classmate who is also redpilled so I mentor her on these issues.
You could redpill the whole class with a few careful questions. Look into the Socratic method. It's basically asking questions designed to trip someone up in their own bullshit.
The most powerful words you can speak to someone are the last words that came out of their mouth.
Just remember what John Lennon said. "If you are gonna tell people the truth make sure you make them laugh when you do, or else they'll kill you."
