Rand Paul has been suspended from youtube for "misinformation". The "misinformation" was a quote directly from peer reviewed, published research that indicated cloth masks were ineffective.
I don't like any of youtube's "curating", but when they do it to media people for making opinion statements or hearsay, even though they only seem to do so for certain views, that's one thing. When they start "curating" PEER REVIEWED stuff, that's outright thought control.
Several of us in this thread have posted links to peer reviewed research, with the various links often contradicting each other, but that's what science is all about. Various researchers arrive at different conclusions, so you discuss and continue research. Once you start censoring and "disappearing" vetted research, not only are you being totalitarian, you're actually crushing the scientific method.
