There is some confusion about the definition of free speech.Universities are not under any obligation to invite people with any conceivable view to speak. What the people who invite these hate preachers such as the president of Iran and Tutu don't understand is that by debating whether Israel should exist they are clearing the ground for our destruction. It is now legitimate to debate the ethnic cleansing of Jews from Israel. Where do they draw the line? Would they debate the pros and cons of pedophilia? Would they hold a debate about rounding up all Afro-Americans and sending them back to Africa? Obviously not. But when it comes to the Jews the rules are different.
