I have experienced a Radical Honesty follower first hand in a relationship. From someone I loved I now can't even be bothered to acknowledge them. My experience of the change in this person was a loving person to that of a 'truthteller' WHEN it suited them, they cheated on me on more than one occasion, and thought because they would tell me afterwards it was cool, because they told the truth! Truth is truth, when it becomes radical truth, 'radical' takes preference and diminishes the value of truth...
