This critique of this argument makes the above point.
It’s a great point, which UD would in fact revise and extend, in this way:
“There are over three thousand four-year colleges and universities in America. That 129 maintain markets in sex slaves has not caused higher education to wither away.”
In other words this is America, dammit, and we’ve got so many colleges and universities doing so many different things, that it doesn’t matter what some small number of them does – the larger national project of higher education is not going to wither away because of it. Only an hysteric would think that twenty or so Tuskegee Syphilis Experiment Redux programs are going to threaten higher education!
