I'm all for allowing discussion of ideas even though they may be disagreeable or offensive, or even unwise, immoral, etc. But debates on this concept always end up at the Holocaust denial level. It's a fine line. Are you going to let someone come in and talk seriously about that, providing "evidence" and alternative histories, etc?
"Are you going to let someone..."
The use of language such as 'allowing' and 'letting' suggests that someone lacks permission until and unless it's granted to them.
If someone expresses a point, supported with evidence and/or reasoning, and is willing to listen to and engage honestly with critics, what grounds would we have to restrict the expression of their ideas?
If a student-run organization wants to invite a particular person (someone from outside the university) to speak at an on-campus event, do you think:
A) The university authorities must first grant permission, or
B) The university authorities must be notified, and given the opportunity to disallow that speaker, or
C) Neither A nor B, but the university authorities can intervene (during) or sanction (after) for breaking the rules/principles of the university, or
D) None of the above.
My choice would be (C). But your comment "the universities get to decide" suggests you may disagree, and perhaps you believe A or B is better?
So while I prefer the spirit of C, in practice I'd choose B - if there's censorship, it should be out in the open. I'd also prefer if none of the choices dominated all universities, to avoid a monoculture.
I live in California, where the court of appeals has ruled that this isn't so:

"We find no basis to depart from the settled rule that institutions of higher education have no duty to their adult students to protect them against the criminal acts of third persons"
If there be time to expose through discussion the falsehood and fallacies, to avert the evil by the process of education, the remedy to be applied is more speech, not enforced silence. -- Justice Louis Brandeis
In that sense, they're not much different from any other rules about something as subjective as which opinions should be permitted. If you follow them too rigidly, you get absurd results.
