Critical thinking is only applicable when you encounter a right-wing meme (turn to CNN to get the correct view on the topic), but when the government puts out propaganda like "There's no way it was leaked from a lab" when there is a lab next to where the virus leaked, we are not supposed to apply critical thinking and if we do we are banned from social media. We don't need mimetic immunity, we need immunity from just accepting that the media/gov establishment party line and that to call them on their BS is "extremist".
