Do you think it's morally right to teach children about one specific religion, but not others?

​If parents have a settled conviction that their religion is true, and not just one viable option among several, and especially if that conviction is that their religion is exclusively true, as Christianity teaches, then it is not just morally right, but morally incumbent for them to do so. This is nothing different than what we do with other aspects of our value system; if we believe that it is absolutely wrong to steal, we don’t teach our children that it may or may not be wrong. If we believe that personal integrity is an essential virtue to maintain we don’t present personal integrity as a take-it-or-leave-it proposition.
That being said, I would actually teach my children about other religions, but only in the context of Christianity, and in the light of Jesus’ statement that he is the only way to God, which renders all other religions as idolatry.
