They say x, ask for where they heard about x. They say from y news organization, ask the source for y. If they say z, if z is actually an actual document or otherwise, ask them where in z does y claim x is true.
If z is just another news organization, keep going until they provide (or don't provide) an actual document. If they can't procure an actual document, send it yourself. If z is just another video cIip, ask them for the whole video. Provide them the entire video if they can't.
Do not try to antagonize. Just simply ask the questions as if you were trying to understand their point of view, to learn something we might not have heard.
Asking questions is analogous to "not trusting the science." They'll also call you stupid for asking questions to what they seem are obvious answers. Normies are incredibly stupid.
This is what I've observed.
Right, and ...
They don't even know what science actually is. They think it is nothing more than a consensus opinion of self-appointed "experts." They do not understand the Scientific Method, which is what science IS.
They think certain things are "obvious answers," and yet they are incapable of explaining why.
They are stupid, ignorant, and lazy.
A person can be stupid, or they can be ignorant, or they can be lazy. But they can't be all 3 without destroying their own lives and the society in which they live.
I should be glad I'm just lazy.
