Several sites I used to enjoy have been ruined by this toxic polarization.

Everything is an echo chamber these days. No one wants to be wrong or look foolish online. People don't want to even read opinions other than their own. There is no more civil discourse.

It's not just online - I'm noticing the same thing in real life.

I don't know how to fix it...but I hope someone does. Whatever the case, we need to treat the cause, not just the symptoms.
