On a campus that is free and open, no idea can be banned or forbidden. No viewpoint or message may be deemed so hateful or disturbing that it may not be expressed. Rather, Paul correctly identifies the issue when he speaks about the proper role of universities. Our difference, however, is that Paul believes every individual should have the right to say, and continue to preach, whatever she or he desires. I would draw the line differently.
Universities are about knowledge, about acquiring it, questioning it, and understanding it.
While ideas are always open to expansion and modification, there are some facts we know to be true. The Holocaust happened. The Pope does not control the minds of every Catholic. Asians do not have a mass conspiracy to take over the world. In other settings, we might ignore these ravings of intolerant and ignorant souls.
