Regarding John Hockenberry

NPR's John Hockenberry is accused of sexual harassment. Two issues: one, he's paralyzed from the waist down so there is no physical threat that can be associated with the charges. Not that that would excuse boorish behavior  Second, from the sample that was read on the radio, the accusation stems from benign emails he sent asking a woman out on a date. Unless there's more, how is this charge be taken seriously?
