It is not an appeal to authority. It is citing my source.

I don't know what your beef is with me. As far as I can tell, both my comments make the same point: That pro vaxxers are just as extremist and close minded as anti vaxxers.

There are lots of people who have bad reactions to vaccines, who take some vaccines but not others, etc. who are not ideologues on the subject. The medical community has processes for dealing with the reality that some people react badly to vaccines and judgement calls need to be made. Pro vaxxers act like this is not a reality. Both camps are very all or nothing.
