There's been a trend around the country of trying to get college to disinvite speakers with a different point of view or disrupt a politician's rally. Don't do that, no matter how ridiculous or offensive you might find the things that come out of their mouths... If the other side has a point, learn from them! If they're wrong, rebut them, teach them, beat them on the battlefield of ideas!
