Look, let me help you out here. First off, you should be asking what they know about the subject and not someone else. Tell them they shouldn't need sources if they aren't informed and if they are informed they should go figure it out and return later and remind you the reasons for which you're wrong. But reiterate that you're having a discussion *right now* and if that's going to continue, they're going to have to suspend disbelief and to humor you for the time being. If they don't know better and are unsure of whether to trust you without good reason, remind them that this means they're simply uninformed and learning more with or without you might be a good idea. Secondly, you want them to think they're the ones that thought of it. You don't *tell them* what's true. You appeal to curiosity: >Hey why do you suppose those guys with the big noses who cut off baby dicks were kicked out of over 100 countries? This is where they ask you what you mean, you repeat it again and then they pause and remind themselves it's bad to be "anti-semetic" and say something about how that possibly isn't true. This is when you ask them, "okay, but is that false? Do you know? Have you ever looked in to it?" They'll inevitably repeat their disbelief or come back later (if they aren't just some junkie with a short memory) and say, "well, Snopes did this fact check and it said that's not true (or at least mostly untrue or whatever their "some part of that is wrong" bullshit), so I'm not sure I believe you." This is when you press them further and say," no seriously, what sources did they use and did you read the source material?" This is about the time they get annoyed, notice the brain block that stops them from thinking further and you get to pull up the source material with a smug grin or they decide you're toxic for making them think thoughts the black box with the pretty colors on it told them they aren't supposed to think. Optimally, they actually start to listen and it starts to set in and they begin to attempt to get to the bottom of it. So, that was super long-winded, but it's more about you posing questions and **showing them** how to think critically. You don't show them how to do so by *telling them* certain information, but asking what they think about X and when they tell you asking them why they think they think that. Have you ever seen a super patient boomer talk to some retard, going super far out of their way to make a point? Or have you ever seen Jordan Peterson maneuver interviews that are loaded with gotcha questions? That's your aim.
