A snakeoil salesman is exposed by the fact that he sells snakeoil. He advocates it, pushes it into your conscience, lies about its benefits and convinces the weak of mind that it is the answere to their every need. Nevertheless, he is still the consumate snakeoil salesman par excellance. A snake in any color is still a serpent with with a poisonous bite, whether he poses as a lawyer, teacher or politician, his bite is lethal to his intended victim(s). Buyer beware this snake.
