Amusing whether you agree or not, from Z-Man at Taki:
Up until fairly recently, it was possible to get along with the crazy aunt or the old left-wing college buddy by avoiding certain topics. The cost of tolerating these mentally unstable people and keeping them from going berserk was to walk on eggshells around them in normal conversation. If you avoided their trigger topics, their insanity was for all practical purposes a private affair. It stayed in their head.
Social media changed this...
