Let's put warnings on vaccines then?
There's just as much (or lack there of) "evidence" that vaccines cause autism as GMO's being harmful.
This reminds me of talks with my dentist. Me: What about mercury fillings, could they really harm you, or is that just a bunch of BS. Dentist: That's crazy. There is nothing wrong with mercury fillings. Nothing. Me: Would you use them for your children? Dentist: What! Never, composites only. The science is really not out yet on that.
An interesting talk for sure. :-)
