That's not what the poster said. You think you heard "censorship" because you want to hear "censorship" because that's what you want to argue against. But please read their comment again. They literally said they don't know the answer.

Also what that poster did say--and I agree--is that people lack critical thinking skills and have not developed immunity to flat-out bullshit. There's a huge education pipeline problem and our society is at risk because its normal resistance would be to have voters that can think for themselves. Things like flat earth and moon landing conspiracy theories don't need to be "not allowed", they just wouldn't take hold if people could think through basic logic.
