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.

So yes, I think flagging "works" along with the other things I do which amount to treating my children as though they are independent intellectual actors. Just as I think flagging "works" in any conversation where values, judgements, and observations might get confused for one another, possibly even by the people who express them.
