Huh? How does this have to do with liberals?
If you posit that the universe is governed by God, and that He has provided a specific way for humans to behave, you can't be tolerant of diversity there. There is the divinely inspired truth and there's error. That's it.
From the perspective of those who have the "truth", there's only two ways to view those in error.
A) See them as intrinsically inferior.
B) Acknowledge them as fundamentally equal.
Taking A) means conversely that the group of those with the "Truth" are intriniscally superior. The responses to the "non-believers" can vary from ignoring them to annihilating them.
Taking B) means acknowledging that those not in possession of the "Truth" have the capacity to gain such possession. Responses vary from doing nothing to missionary work to forced conversion and execution of those leading others astray.
but in no situation can someone who subscribes to such a religion hold that the other group's different set of beliefs are just as valid as his own. After all, it's not belief, it is the One True Way.
Tolerance is not a virtue; at best you get inaction.
