The other threat to the security of our tradition, I believe, lies at home. It is the current fear of radical ideas and of people who propound them. I do not agree with extremists of either the left or the right, but I think they should be allowed to speak and to publish, both because they themselves have, and ought to have, rights, and once their rights are gone, the rights of the rest of us are hardly safe.
