Mr. Hafner;
There is a name for the reality you are denying.  It's called "stochastic terrorism" (look it up).  And NO, I do NOT think ANY of "old Bernie's rants might have triggered him..."  Your desparation to deflect blame for  racism on those who are fighting AGAINST racism, against ethinic violence, against religious enmity, comes across as a thinly disguised defense of racism, ethnic violence and religious enmity.  YES, Sarah Palin, and Bill O'Really?, and Donald Trump ARE enablers... dog-whistling "suggesters" that "hint" at a renewed nod of  approval for the primitive, disgusting, ignorant traits of racial, ethnic, and religious, hatred.  It is becoming evident that Trump supporters and the right-wing Confederates want, and are working FOR, a divided America in order to advance their form of authoritarian ideology.
