History shows again and again that regulating speech just doesn't work, and has many negative consequences. The best thing is to leave people be to talk and interact. People are not machines that can be controlled so easily. If they cannot talk in an open way, they'll conspire in a hidden way, and possibly even resort to violence as a remedy to the oppression. They'll use the oppression to justify violence, and to gain sympathy with their cause.
