[I think that precludes this being brainwashing without consent. ]
Neither does it preclude ‘brainwashing WITH consent’. Say you had a 15 year old daughter who got a hankering to become a Scientologist. Would you think her competent, even with you present, to have an auditor come over for six sessions? Just so you could get her married off to the son of a presidential candidate?
More to the point though, has the marriage been a sterling success? Yes, I think you could say that and Ann is no shrinking violet in the Mittster shadow. She has five very fine sons to show for a successful household, too.
