OP’s point was that the argument in favor of vaccines needs to be made more convincingly. What does that actually mean? How could the information be presented more convincingly?
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.
What specifically is lacking in the pro-vaccine argument? I'm not asking about censorship, as it is seemingly a moot point. OPs point is that the argument needs to be made more convincingly and spoken louder. What does that look like in practice?
