Muslim Brotherhood can't be said to be non-violent

I am not in favor of banning the Muslim Brotherhood, naturally, when the terrorist organization, known as Friends of the Israeli terrorist army is legal in the US.  But it is not accurate to suggest that the Muslim Brotherhood is non-violent.  It has been quite active through armed groups in Syria, having renounced violence in previous years. So their declarations can't be said to be truthful.  And the Brotherhood is also active through armed groups in Libya.  As for the fact that the Brotherhood spawned a variety of Jihadi groups, it is a fact.
