It's almost like people without fully developed brains don't have very healthy social interactions in a giant soup of similar kids who don't know how to have healthy social interactions and the 4chan-ness of it just encourages being as angry and toxic as possible.

It's actually probably the same problem drivers face. When driving, your brain kind of ignores that other normal humans drive the other cars, and therefore you are extremely judgemental of their actions, because you expect them to be perfect. This is why so many people road rage.
