The President at first very appropriately not only condemned one moron from the right but all the A$$holes on the loony violent left who had been clubbing folks who disagreed with them.   I think the Fake News Media is trying to start a civil war.  They might want to consider that many on the right not only have weapons just like the leftest thugs but got them and learned to use them.   Then look at our highly trained professional military and the high percent who lean to the right. 

Keep in mind Robert E Lee was a highly respected officer in the US Army before he was forced to take sides and chose his home state.  If he had the manpower and industrial resources available to the North we would be two separate countries today..  The argument was not slavery it was dying a slow death keeping slaves was expensive compared to the abusive employment of Irish emergents in the North.  The argument was as old as the Union could individual sovereign States leave the Union.
