As one who has friends who are believers in Islam, and arabs, and even relatives of this ilk, as well as real communist ideological believing friends, may I just point out that Dal obviously is just a poor damned ignorant fool who buys everything he is told by organized change-agent advocates. He's really a very decent human being, otherwise. Well, obviously, it's a stretch for me to use the word "everything" when actually it might just be some things which he is committed to not taking proper objective issue with. Oh, where is OB when we need him????
IMO, the thugs who are trying to stir up violence at Trump rallies are bought-and-paid for stooges, paid by the like of George Soros, whose interest is in accumulating personal political leverage within our system, for his own benefit. Soros wouldn't care who gets hurt, or killed, to gain that effect. Trump, on the other hand, doesn't care if you like what he's thinking or not.
The best thing real liberals with nice ideals about making the world better could do is rise up and condemn this kind of exercise, no matter who starts it.
And, as a now=dedicated Trump supporter, I call for Trump's fans to stand down. Take a few hits, just don't respond in kind. Trump could be the new Gandhi.
Vote for Trump.
