That led to a discussion about vaccines. (I love being able to talk to people about vaccines, but I also know it's not at all fun to learn. Ignorance is definitely bliss.) I said: I don't encourage you to look into vaccine ingredients unless you're prepared to be grossed out. Apparently he was.
Incredulous, he asked: Why hasn't anybody told me this before?
If doctors really did offer informed consent, as they are ethically supposed to do, would any loving parent really sign up to inject those toxins into their kids? Does anybody who knows what vaccines are made from and how they're made still vaccinate their kids or themselves?
In my idealistic world, nobody would. Fear motivates a lot of people to do things without looking into them. Education is the enemy of fear.
