Threats are now "freedom of speech"

[thir]

As long no one follows through, they aren't responsible. But communicating a threat is illegal in most states. Judicial mileage will vary. There are extremists on both sides of the issue. By definition extremists are not examples of the rest. Those who prefer to stifle any dissent will always group all together with the extremists so as to dismiss legitimate debate.

I understand what you mean here, but then again it is the extremists that catch the attention and start the debate, isn't it?

“They will know your habits and routines. They know where you shop, who your friends are, what you drive, where you live,” the letter said. “You will be checking under your car everyday — because maybe today is the day someone places an explosive under it.”

To me this is not debate. There is no arguments or discussion or voicing an opinion.
There is only harassment.
