No I mean Muslims do not have the chance to venture out of the their belief system and think about what other religions have to offer. Doubting their GOD is a sin, they do not have a margin for doubt or free thinking in a religious sense.
They are far from being perfect in this sense. They are just not allowed to doubt GOD. The only Muslims that I have met who were really interested in learning about other religions were the one's who never go to mosque and who eat pork.
