My kids do have opinions that differ from mine, and they do it matter of factly, without thinking it is a particular sin or threat to our relationship for sure. At least one of them, when I explained a cryonics thread, allowed as she believed in some sort of life after death and thought cryonics was irrelevant and even a negative in that light.
