Anyone who knows anything about toxicology knows that the dose makes the poison. Furthermore, the form the element takes has a huge effect on its toxicity.
Just for fun, look up sodium metal. It's nasty stuff, yet I bet that even after reading about its dangers, you will still eat salt...
And so what if some symptoms of autism and some symptoms of mercury poisoning are identical? That means nothing.
You mentioned taking a Philosophy of Science course. Didn't that course cover issues central to science, such as critical thought???
As I said in previous post, the EPA lists Hg (ethylmercury, methylmercury, thimerosal)toxic levels to be 0.1 micrograms. One vaccine had 12.5 micrograms.....You do the math and how on God’s earth would you think that something so toxic could be given to a 4 lb. baby.
BTW, I love salt.
