It seems to me that if you had an apartment with the following students:
- active, believing mormon;
- non-believing, but still on the records mormon;
- born-again christian;
- ex-mormong (name removed)

and they were debating, say, female ordination, three of those kids would be free to say that they disagree with church policy, and one would not. The only difference is that one took his name off the church records. I don't see why the rule should work that way. Why do we think that the voice and opinions of the ex-M, who STILL WANTS TO BE AT BYU, is a bigger threat than the born again, the non-believer, or the believing liberal?
