cyberbullying

Science communicators are routinely harassed and threatened, not just by the Twitter mob but sometimes by allegedly reputable professors, journalists, and even other science communicators.
If we can tune out, move away from, and shun people with whom we disagree, is this course of action also acceptable? 
Once the weapon of choice for prepubescent teens, cyberbullying is now deployed, with ruthless efficiency, against PhDs who have committed the unspeakable crime of conducting research on, and publicly advocating, GMOs. The goal is straightforward: Biotech scientists must be destroyed professionally. Failing that, they must be destroyed emotionally.
