Trying to get a handle on the issues here, needless to say, I wouldn't mind seeing FB taken to the cleaners while still respecting our right to freedom of speech; but wrong is wrong.
At the same time, FB is voluntarily taking down pages which can in any way be perceived as critical of Islam, Muslims, or the actions of Muslims (including terrorism) and Muslim immigrants. This was at the request of some Muslim organization. FB already censors heavily - just not what it should.
