A public university has a rule that any speaker that speaks at its open forum is prohibited from knowingly making false statements of fact as part of any presentation or lecture. At a lecture, a speaker claims that he has a PhD from Caltech and has written several articles on quantum mechanics. In fact, the speaker never graduated from college and has not written any articles. In an action challenging an order banning the speaker from speaking at the university on any subject, which of the following arguments would be the least accurate: A. A designated public forum is not created because the university allows only selective access for individual speakers. B. The university's determination as to what is compatible with its educational mission is entitled to deference even when the university creates a limited public forum for some speech. C. False statements are not protected by the First Amendment. D. The ban does not infringe on the speaker's constitutional right to speak because there are ample other venues for him to speak
