I'm not so sure about that. There are some people who take seriously the fact that they could be wrong. They approach discussion with an open mind, listen to the other, look at evidence with a critical eye, and respond fairly.
Others come to a "discussion" from a totally different headspace. They are bitter, angry, and, to be frank, not very smart. It's not discussion they are after, because they aren't open to the possibility they may be wrong.
My theory is that this is the "rabble" that used to be led by the church, and then by mass media, and now by internet media. The internet is fractured into close-minded echo-chambers, and for many alive today, the classic error-modes of public online communication are new and exciting. The right is enamored with the brutal effectiveness of trolling. The left seems to prefer doxxing and blacklists. And internet companies care about metrics that don't capture any of the externalities of their platforms.
Hopefully they'll all grow out of it.
It is so hard to imagine how they just cannot seem to understand why you are right, despite all your trying to teach them.
But then you imagine that they must be thinking the same thing.
I cannot imagine what must’ve gone wrong in their lives that so many lies could be built on one another.
