The problem with what you are claiming is the people who were censored were Doctors and scientists with academic cred....you know, as you said, attempting to participate in scientific debate on social platforms.
Robert Malone was one who was censored, he was a co-developer of Mrna.
There was a fair size group......any counter view, other than the official CDC/Big Pharma was rejected and the media stepped in, attacking these people....so much for scientific debate.
Robert Malone is vaccinated and boosted. He admitted to it. Why didn't he take ivermectin if he believed in it so much? He was a scientist at some point in his life. Now he's just a shady con man.
