@freemo Any phrase used as a tribal identity marker tends to attract stupidity because the point is allegiance not analysis; any topic of considerable depth discussed in 280 or less character chunks tends towards stupid because there isn't enough space to advance sufficiently nuanced ideas; and in this case the starting point is counterfactual, which poses serious challenges for non-idiotic support.
So, yeah, if it was anything other than a maelstrom of stupidity, we ought to be mightily surprised.
(I do note with displeasure that a lot of people more on the sane side of things tend to overestimate the degree to which one can conclude things like "vaccines are totally safe" from observations like "the anti-vax side is comprised of idiots". That's not how it works! Is there a talkorigins.org equivalent for Covid vaccines yet?)
