Once is gag, more than that is potentially a problem. Believe me, I know. I worked closely with a powerful person who had this issue. When you couple it with the fact that he lived with two gay men, one of whom he kissed on the cheek every morning (or so reported here on FR), it raises serious questions about his fitness to be the leader of the free world. Downplay it all you want, but unless he’s had an honest psychological evaluation he is willing to make public, we’d be playing with fire.
