You do realize that there is a difference between an antivaxxer and someone who opposed to the COVID-19 vaccine, don't you?
Antivaxxers are found in all political parties. No one party has the corner on antivaxxers, however, I think there are slightly higher numbers in the Democrat party but that is just a guess and I don't know for sure.
People who are opposed to the COVID-19 vaccine are mostly blacks, Hispanics and Republicans but not all of them.
My wife is a registered Republican and she has had the vaccine. I am registered in the Constitution Party and I also am vaccinated.
We both believe that the vaccine must be by individual choice and not forced by any kind of legislation. Especially when the vaccine, they are finding out, is not as effective as once thought. And even less effective on the delta variant. So forcing people to inject something into their body is rather pointless.
Freedom is the only value that is worth more than life.
