That will be one hard law to enforce!! Certainly communicating threats and harrassment is the easy part. It would be enforced the same as making a threat over the telephone. However, almost everything else is going to come into a very grey zone. I think we need to be careful of knee jerk reactions especially when we are talking about free speech. That liberty is already under fire in other countries and in the UN where certain dignitaries have suggested that the United States limit free speech when it comes to denegrating religions. This comes, of course, as a reaction to that dumb movie about muslims. A real slipperly slope to play on.
