"Really? Do you even know what he meant by "stick it" in this context.?"
Oh, yes.
"If you saw, say, a Scientologist or a Wahabbi on a streetcorner handing out literature, you have the freedom to "stick it" to him by handing out debunking literature, engaging in debate or even mocking."
Acctually, your freedoms in that area are not without limit. For instance, he may not want to debate you, and if you refuse to leave him alone, your behavior might be criminal. Mocking, as well, is in many places regarded as provoking speech, and in some jurisdictions you can be arrested for that.
Further, this took place in a state school. Your position is tantamount to arguing that it is a violation of separation of church and state to promote religion, while it is perfectly permissible to mock religion with public funds.
"You do not exactly have the freedom to lie"

"You do, as with the case with the prof, have the freedom to point out the flaws, inconsistences, lies and whatnot in your opponents worldview."

His comments were cited from a Yahoo listserv. How does this involve public funds?
