"because of their scholarship and reputation. "
Churchill's scholarship is shody and his reputation is as a hate monger.
"Why gag free speech?"
You seem to be completely ignorant concerning the definition of free speech. It means that you are enbreastled to say anything that you want. It does not mean that you are enbreastled to have someone pay you a salary to do so.
"If he is wrong, then prove he is wrong,"
Another idiotic remark. How do you prove or disprove statements like "The 9-11 victims were like little Eichmans" or "The US should be removed as a country from the face of the earth"
"Clearly you don't support the principle of free speech and open debate."
What and who will stop Churchill from exercising his free speech and open debate when he is no longer a professor. This question is not about free speech. It is about who should be forced to pay the salary of an idiot phoney Indian wannabe like Churhill. I am a Colorado tax payer. Churhill doesn't pay me to express myself. Why should I pay him? The overwhelming majority of people from Colorado don't want to pay Churchill's salary. Who the hell are you to suggest that they should be forced to.
