Crazy lady accuses Barney Frank of supporting Nazism.
In the words of Montell Jordan, this is how we do it.
How one responds to hateful, lying, self-righteous, self-deceiving, belligerent fools depends on one's role and one's relationship to particular fool in question.
If this woman were your sister, mother, daughter, student, teacher, doctor, patient, cab driver, neighbor or village idiot then your particular responsibility based on that particular relationship would vary accordingly. But the first step, when confronted by a malicious smug-drunk liar like this woman, is to do what Frank does here — try to sober her up with a splash of cold water and then remind her of what she already knows, that she ought to be deeply ashamed to be behaving like that.
