So, the scientist up there is telling you that the antivaxxer is wrong or right or half-right on numerous points. Whom are we supposed to believe is correct? The person who has who has read something and has grasped "something" or the actual expert who is correcting the "something" the person is espousing?
That scientist didn’t provide any references or explanations for her ‘counter arguments’. She is no different from a regular pedestrian.
The only thing that makes one an expert is the ability to provide more insight based on real life experience than a regular person would not get from reading published material.
That’s why I said that scientist and the antivaxer are no different from that video. They’re both making unsupported assertions.
