Ken King, the antivax maniac in my previous post, is back. The man is a glutton for punishment, especially in view of his adherence to Colloidal Silver, an inneffective quack nostrum whose most notable effect is to turn people blue.
He's really a very angry little man. And he's utterly unwilling to be swayed by rational argument, believing as he does that vaccines are not only 100% ineffective but also staggeringly toxic. So the only alternative is to have fun while provoking him into making a fool of himself. Not difficult.
