You describe a type of person that I know well. It's incredible, it's a stereotype in fact, quite common, they all seem to act, or react, the same. When you talk face to face with them, they don't tell you to watch a couple of videos, but to read one or several books that they probably never read in first place.

You can logically rebut all their points, and the next day they will have forgotten, talking to them is plowing in the sea. But they are very emotionally open and they take everything personal, in matters where they should not do that, becoming very vulnerable to what one say. A discussion can be a torture for them, and the opponent can increase or appease their emotions easily by saying one or two words.

But really, the best way to talk to them is to put yourself on their side and based on that, show them why you think as you think. If you want to convince someone of course.

Of course, just one or two thoughts to add to what you said, if it was not already clear. Regards!
