It's simple: "The only way of living in a free society is to feel that you have the right to say and do stuff." Said Salman Rushdie. Go figure. Let truth and falsehood grapple. How do we know what is right if we don't know wrong and the case that is made for wrong. Ideas may be distasteful and deeply disagreeable, but we cannot airbrush and disappear that and those people that we disagree with.
