to ASK for the Privilege of going to BYU. Part of the price for that is attending Church. They are free to go somewhere else if they are not interested or willing to pay that price. I knew plenty of people, who for one reason or another, transferred over to UVSC (at the time). It isn't that hard. It is of course much easier to just go to Church. But no one is forced. BYU is VERY upfront and clear about what is required. Thousands of people have, and do live the requirements. It isn't that hard. If you are not interested in that, then go somewhere else. There are plenty of kids who will go to Church and live the HC.
I don't see where anyone is being forced in this.
