I think Cal is least "tolerant" in that if you don't agree with them they are most likely to stand up and yell and make a fuss about it.

BYU isn't flexible but they are more "tolerant" in that they will allow people to make whatever choices, just not be absent the consequences of those choices if they are contrary to BYU standards. Cal is intolerant of letting others even have opinions or make choices they view as "intolerant". So while both BYU and Cal may be regarded as intolerant, Cal is hypocritical about it while BYU advertises their stances. To me, that makes Cal more intolerant.
