I am also reminded of the Voltaire quote "Those who can make you believe absurdities can make you commit atrocities" and "The road to hell is paved with good intentions"

Good intentions can be misguided by manipulating the info-space using the twin tools of propaganda and censorship. "I don't hear anyone or any expert contradicting this and it keeps getting repeated so I guess it must be true. Not sure if it makes sense to me but I guess I''ll trust the experts." The masses can go along and help commit atrocities thinking they're doing something good or necessary.

It's hard to get a majority to believe absurdities and to keep them believing it without employing mass censorship.
