I see, Always Right Rob is playing another one of his language games. He warped the actual argument, which is "illegals are (shouldn't) be receiving Medicare/aid" into he wants me to prove I specifically have seen it. And I'm supposed to access databases, people's medical records, etc.
I do have to point out that neither Rob nor anybody else on here demanded such info when I posted (pro-vax) anecdotal evidence of what I've seen in regards Covid. That suggests Rob doesn't vet information that supports his world view to the extent he vets information that contradicts his world view, which further suggests he works backwards from taking position and fitting in the evidence into fit his preconceived notion (otherwise, he'd vet information equally).
Furthermore, since none of the anti-vaxxers asked for this level of information, it seems that they understood that would be a violation of the social code, job policies, etc. Or if they didn't understand or care about social codes, job policies, etc, they at least placed more value on higher level data (ie CDC data) than my anecdotal evidence.
