The station manager knows him as well as he knows himself I'd bet. It's about money lass, not truth nor even right and wrong. It's all about making people listen to advertising, not education. I'd be stunned if he cared, and doubly stunned if the station sent you anything more than a form letter that seems personalized, if anything at all. We got letters like yours at radio stations I worked at. They always made it to the circular file, generally before the addressee even saw the envelope. By all means do what makes you feel good, but imo you're throwing a water balloon at a forest fire.
