Donald Trump is not Gandhi. When he is attacked, he fights back. When organizations like moveon.org, supporters of Bernie Sanders, organize an attack intended to deprive Trump and his supporters of their first amendment right to free speech and freedom of assembly, when they attempt to disrupt and shut down Trump speeches and rallies, then Trump and his supporters have every right to defend themselves. The fact that the media, the Democrats, and even the other Republican candidates are all spinning this self defense as Trump being responsible for the violence directed against him, is remarkable.
I predict it will backfire. I for one do not want a President Gandhi. I want a President who fights back when we are attacked. I want a President who encourages Americans to stand up for themselves against terrorists and invaders.
