The people that still support Fauci and the rushed to market, limited benefit mRNA product after 6+ years of information do so because they aren't capable of admitting that they might have been wrong about any of it. To do that, in their mind, would be perceived as weakness and an affront to their ideology and yet still publicly state that everything done during the "pandemic" was done to perfection.
I will admit we had no idea what we were dealing with when the virus was first released and the measures taken then seemed justified given the circumstances, but science isn't stagnant and many of the protocols initiated then have been proven useless.
And make no mistake, the vast majority of Fauci supporters are of the liberal persuasion, that would fall on their sword rather than concede anything.
Sad, that those that screamed follow the science the loudest are now ignoring it.
