Those "few thousand" - which I think is probably high estimate, pulling out of my rear..... tickets could be gifted to someone (or sold) to someone who would be in the seats and buying products from vendors. They were already purchased - those season tickets, so it's no financial loss for the university, if those of the jewish faith did not attend - especially when you consider the vending arrangements and the Rentschler Field relationship with the university. No - I think it was a pretty selfish thing, in retrospect, by a minority of people, to request that the game be moved.
On another note, I can't imagine that it's easy to be of such different beliefs with your wife, and I hope that it is not difficult for you. As for myself, I can say that I get shunned terribly when I choose a UCONN football game over one of the younger people in my family's sporting events that tend to be scheduled for Saturdays, and I have given my tickets up to others in the past, in favor of those events.
