When someone is seriously maimed, injured or killed during these riots the call for peace will happen, but until then we're just going to have to sit back and wait for the tragedy. The blame will sit squarely at the feet of the left.
How did you come to that conclusion?
Has HRC or Bernie suggested slugging someone in the mouth? Used fighting words in their stump speech? Incited violence at a rally? Trump has.
"The left" is a vague term, one used primarily as a pejorative to describe all who do not walk in lockstep with the new iteration of conservatives, those who have tossed under the bus moderate and centrist members of the Republican Party.
There is a far left, but it is not part of the establishment. They have fallen off the fringe of the Democratic Party (see: Socialist Worker's Party)
