My point is that the argument can't be made more convincing if the argument isn't allowed. Even if the information all points in one direction, and at this point it more or less does, I see it being presented in a way where any questioning or dissent is actively ridiculed or repressed. This naturally causes suspicion.

Instead of presenting the vaccine information as a flood of not to be questioned, yet well meaning, propaganda I'd prefer an open and honest dialogue that meets an individual where they're at.
