When Echo Chambers are Okay

Some people, when faced with an argument or some data that challenges their beliefs, simply get angry. I'm not a psychologist, so I don't know if there's a name for this, but I assume it is why some people have to take anger management classes.

These people are out there, though.

They are physically incapable of engaging in rational discussions.

In cases where most people would reconsider their beliefs or formulate a counter-argument, these people can only respond with rage.

It would be interesting to see how this type of person form their opinions in the first place.
