I know many people use this as an anti-vaxx arguement, but I think it goes beyond. I believe there is more to it than just vaccines, it's also all the chemicals in products, hormones, pollution, and genetics in general since genes are passed on. Not to mention over 2000 nukes have been detonated and radiation spread around the earth. I also think that conditions other than autism but also are occurring more frequently these days fall into the same category, like gluten intolerance, peanut allergies, lactose intolerance, etc. Go back 50 years, many of these things never cropped up more than a few times although they were known about and diagnosable. And before I get labeled, I believe vaccines do more good than bad, and many of the products out there are good products that have bettered mankind. I just realize that many things have happened that could be contributing to more terminal illnesses and conditions, and admit I am not an authority on any of this.
