Tolerance of intolerance should never be tollerated.
They should be labeled as a hate group and disbanded as a "group" or "organization".
Of course any government action like this, it should require a extreme openness with the public on the process and the decisions so any such power is never abused.
I guess i'm not really for stepping in and breaking them up as a group over this in particular, but their body of work leaves a large distaste. And they should be definitely officially labeled a hate group.
And i'm largely for free speech, but speech that incites action, negative action, should have consequences applied to it. As long as they protest peacefully, in this instance, i'm not as offended. But protesting the funeral of soldiers was another level of disgust.
