Social Media as Mob

Social media has become a scary tool for mobs intent on silencing or, worse, destroying those they don't like or with whom they disagree. IMHO, this tendency to mob antagonists has been emboldened by the laxity with which many college administrators have dealt with students who wish to shut down conservative speakers. Several issues are at stake:
1. Free speech
2. Endangerment of the targets of mobs
3. Economic destruction of the targets of mobs
4. Inculcation of a sense of entitlement and invulnerability in college students

There need to be legal penalties for this sort of mistreatment of people.
