I have asked antivaxxers that I have met why they don't get vaccinated. They can offer no decent reason other than " just because ".
I note that all these people take/have taken various medications in the past, had hospital treatment on occassion, eat and drink processed food, live in normal houses in the presence of various manufactured toxins. In some cases, some of them smoke cigarettes.
If they were people that lived a genuine toxin free organic life I'd cut them some slack. But, they're not.
As I have said all along. If someone chooses to not be vaccinated then they should accept the restrictions that come with that. Just like smokers etc.
