The name we have for that group who think they "know better" is "Scientists;" they're intellectuals who use their powers of observation and rational thought to methodically discern oft-hidden truths*. You can ignore them, and I won't stop you, but you should admit, at least to yourself, that to do so is an irrational self-destructive act. Don't be surprised when people push back against your verbal elevation of wrongful harmful memes.

You're correct in one sense-- It IS about control, specifically, how sociopathic corporations now control and subvert institutions of public health and regulation for their own wrongful pecuniary interests in unending acts of manifestly depraved avarice.
