Censorship isnt the answer, its playing their game. Best to do. Pressure legally, swiftly and societal pressures are better ways, if someone insites violence using codeded language that should also be taken into account. Anyone who is not turning from the violence in my opinion should be in jail or an asylum depending on the mental health of the person. (Usually not a good sign if they want to harm people) but NEVER CENSORSHIP!!!!

Edit: wanted to add. You dont remove your childs tonge when they hit you. You sit them down tell this no that is unacceptable behavior for these reasons and because of that you are going to be punished equally to what you did. These people have gone without punishment or consequences for too long.
