Its not just one or a few people that one guy disagrees. Sorry but the openion of a guy with no experience or professional degree in a field is not the same as people with 20+ years of experience and a phd. And the openion of a piedratician is not applicable to an epidimic as someone with years of experience in that field. Least of all, the openion of a politician is completely irrelevant to anything where they cannt back up their claims with expert sources.

Don't Strawman and generalize - provide an argument relative to this context, if not then the merit of your argument stops by simply changing the content. For example if we were to insert Hitler now your generalized argument looks ridiculous because of course the problem is that people agreed with Hitler.

When a person's opinion is based on literal fabrication of information, based on soley on belief, and is irreconcilable with the truth, yes, the problem is absolutely with them and parties involved.
