Welcome to the University of California: There will be no sexual nudity at any time and no potty mouthing between the hours of 6 a.m. and 10 p.m. And if you need to tinkle, please get a bathroom pass from acting Assistant Vice Chancellor of Student Life Gary R. Ratcliff.

OK, that last one we made up. But the university’s new appropriate use policy governing broadcasts over Triton Cable — announced by Ratcliff in response to the Student-Run Television porn — is no laughing matter.

For years, UCSD has had few qualms about selling students overpriced, greasy food in the campus dining halls despite the nation’s obesity epidemic, or delivering misogynist magazines over university-owned mail services. Yet on the issue of SRTV porn, the university seems to have found religion.

We own the cable, say university administrators, and we can do with it as we please. The problem, however, is that campus residents are the ones who pay for it: The university currently offers residents no way to opt out of subscribing to a service with rules they most likely (judging from the A.S. special election) oppose. (This may be by design; who in their right mind would voluntarily pay to watch reruns of “Parkinson’s Disease: Treating Off Times” on UCSD-TV?)

Nevermind the philosophical implications of regulating morality, or that students can still get explicit porn on Triton Cable’s HBO. If university administrators want to ban nudity, they can, as long as they — not the students — bear the costs of the decision.

Administrative Computing and Telecommunications installed equipment that allows campus entities, like Thornton Hospital, to opt out of some Triton Cable content two years ago. The same option — along with a refund — must now be made available to students.
