Campus Excommunication 

The anti free speech movement in the form of trigger warnings, safe spaces, disinvitations, cultural appropriation, and firings seems to me to be little more than a secular version of religiuos excommunication; banishment and even persecution of people who don’t hold the right beliefs or think the right thoughts.  

In human behavior there’s nothing new under the sun.  We merely name or rationalize it differently depending on whether it supports or contests or favorite ideological team.  

Is ideological excommunication ok or not?

If you think not then you should be against trigger warnings etc.,and any other tools of banishment.
