You are no different than the folks and organizations you profess to despise. The question was about protecting a child against polio without vaccination and your answer was "the answer to that question is complicated?" Then you try to sell a video tape? Hmm. Looks like the pot calling the kettle black, only you are a bit worse as you are urging parents to not vaccinate and putting their children at risk of death. Tell you what, let's go visit a few old cemeteries and read the stones, lets go back to the dates before vaccination. If vaccination ceases, it might be a good idea to buy stock in a casket manufacturer, one that specializes in little white caskets.
