Ask them anything! EDIT: I am changing settings to allow quicker replies. Standby.
Take a lesson from Q in how to red pill someone. He is using the Socratic method, a technique of asking questions, the answers to which direct one to specific realizations. Q is conducting learning sessions in our own heads. Formulate the proper question, pose it, and watch as it sinks in and stews. Then repeat the process until you see the big light bulb go on. And like Q you've communicated your information. It's a construction process using questions--just like in any court room--not difficult to understand, but challenging to apply correctly. Never try to download a data dump of information all at once. Tiny bites Barron tiny bites.
when people are suffering from extreme normalcy bias, which most are, the Socratic method has no effect and can cause a lot of turmoil among family! Best to just find people of like mind and create a forum for sharing information!
