They've been building the vaccine mandate brainwashing for decades too. Vaccines were already pseudo-mandatory for schoolchildren or healthcare workers depending on the state. The reason there's so much opposition is because they're backing people into the corner with it as they try to close more and more exemptions. I think they also lost a ton of buy-in when they started the talking point that the vaccine was to keep others safe. They practically begged people to then ask if the vaccine even worked. What they have succeeded in doing with great success is get everyone debating about vaccines and treatments and whatnot when they have never even demonstrated that there ever was a virus that was both distinct from and more dangerous than the common cold.
