While i can appreciate your enthusiasm, the goal is to move beyond individual opinion and attempt to locate fact based evidence. The INTA survey would fail any criteria taught in the most basic statistics class. The margin or error is so large as to render the study conclusions meaningless. It is all the more dangerous given it having been issued by "INTA". If it had been issued by any other entity i am sure you would have laughed it out of the room
