I guess they don’t require you learn logic to get a graduate science degree, if you are resorting to such poor argument.
If Hillary Clinton and Bernie Sanders believe the sky is blue, would you have to assume to that the sky is not blue?

Every state in the Union except 3 have some form of religious or conscience exemption to vaccination (the only meaningful kind, since medical exemptions are almost impossible to obtain).
It isn’t about what the socialists believe, it is that they believe that the power of the state should be used to force invasive non-emergency medical treatment on every living person in this country.
There are no independently funded, double-blind safety/efficacy studies of vaccines, or their ingredients.
