Not really. You'd be surprised how many people believe that. They need to make informed choices. The way to do that is to say "the benefits are X and the risks are Y". If they have trouble understanding X or Y, you do whatever is necessary to help them understand.
What you don't do is say "Oh COVID-19 vaccines? Yeah, go ahead, nothing to worry about, they're completely safe". It's not up to you to determine that they are safe, the patient makes that judgement. One person might consider them safe, another might not.
> since everyone is smart enough to make their own choice
They don't have to be "smart enough" to make choices. Unless they are mentally impaired to the point of dependence on a legal representative, they have the autonomy to decide about any matter regarding their own bodies. Even if they are uneducated. They could refuse it simply because they don't like vaccines or even you personally and it's your duty to respect that.
Unless the patient is literally dying right in front of you, there is no case you could make for overriding their will on any medical treatment, and even that varies by nation.
> so why be upset about it?
Because it's unethical and undermines trust. When you do this, people notice. They immediately stop trusting you and start actively resisting you instead. As is their right.
> when exactly where they lied to if you claim they're smart enough to dissect the nuance?
It's still a lie. Detecting the lie does not somehow invalidate the fact it is a lie.
> It's obvious the messaging landed on was chosen was to maximize the individual choice to vaccinate as that was reasoned to the best possible outcome for all.
This is inducing people to pick the choice you consider correct. This is unethical in the medical profession. Ethical conduct is to present the facts and let the patient decide. You don't "maximize" any outcome, nor do you "reason" about anything on behalf of the patient. To do so means you are prioritizing concerns other than your patient's best interests and once they figure this out you are done.
If necessary, you can and must use simpler language to help them understand complex concepts. What you cannot do is decide for them in advance and then misrepresent facts in order to manufacture consent for the intervention you favor.
