It's the extreme power differential that matters, as you well know. Why are you trying to defend Bill Clinton? Monica was one of the absolute nadirs in the history of the American presidency. What is your goal?
Can you imagine the reaction of Ronald Reagen, Dwight Eisenhower, Abraham Lincoln, or George Washington if a 19-year-old intern had snapped her thong at any of them. I strongly suspect the thong snapper would be summarily sent home in disgrace. Which is the appropriate and ONLY reaction that a President should have! Any other action by the President of the United States is a disgrace! Clinton is utterly culpable, utterly contemptible, and was deserving of removal of office for involving himself no matter how tempting, no matter how questionable the morals of the young person. It is not a question who started it, it is not question of the character of the intern, it is a question how the President should conduct himself and of his character!
