It is because your are extremely arrogant. You post that you know data and that the people that wrote many reports, published and practiced hands on simply do not stack up to your arm chair analytics. I do not care if you have a degree... so do most of the researchers that wrote those reports.
Just on this. People think here that I am preferring my analysis over that of these antivaxxer creeps. Well, in some cases I do.
But I don't rate my analysis highly - I am following the experts - and I am certainly not myself an expert. The difference is these antivaxxer creeps (also not experts) have the arrogance to think that the vast majority of those working in an area for real (e.g. vaccine surveillance) are wrong in completely obvious ways, or corrupt, and only they can see it.
It is not my calcs viz the antivaxxer creep calcs. I am just reminding everyone that people whose job it is to do this stuff do not agree with the anti-vaxxers. And, often, it is easy enough to see why that I can explain it here.
That is not me thinking I'm clever. It is the antivaxxers actually being astonishingly unclever.
