Why does it need the "extreme" adjective?

From the Googles:

> the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political aims.

Is there any question that's what happened here? It's too bad that we have to worry about "turning off" some sensitive people whose feelings will be hurt if we call a spade a spade, but it sure doesn't feel like appeasing them has done much good, either.

Again, is there any question, whatsoever, that violence and intimidation were used here, in the pursuit of political aims? They 100% want to put the fear of violence into legislators in order to get their way.
