"The schools are "showing: this production?
Are their Theater Departments putting the play on, or is the play being allowed to be produced at the university campus?
Either way, so what? If the students don't wish to see it, they won't go.
I suspect that this production is "making the circuit" and university venues are the only option. It probably doesn't draw enough to be put on in the larger markets.
Bottom line: I think you're either overeating or trying to make some "point" about Catholic Schools.
It's worse than you imagine possible, apparently. Some courses are MANDATING attendance. All the colleges listed, IIRC, are providing funding for the performances.
