> How does a reasonable, good person end up warped like this, where they assume that every person out there is a bad faith actor? Where there’s absolutely no scope for disagreement? My theory is that Twitter warps people in this way, by simply removing any scope for reasoned discussion. When you only meet trolls, and never have any friendly discussion with different viewpoints, you assume that a person disagreeing with you is a troll.

Also, nothing sells like negativity and sadness. It's highly engaging material. In my opinion they're just selling the same old goods. The only difference is that the cost of goods is now you.
