The bottom image is pretty much why it's funny to me.
Apparently for dudes who've got a compulsive need to be the smartest person in the room, "someone who's wrong in a really stupid way who has unshakable confidence that they're smarter than you" is their kryptonite.
Tons of people keep trying to convince him even though he's just saying "no you're wrong" over and over again.
The point is that when you're an adult and talking to a child, you can't talk to them like an adult. When you're dealing with someone without the faculties or desire to engage in informed debate, just save your breath.
Actually incredibly instructive to US readers at the moment given our horrific levels of education and high levels of misinformation and bias in media.
