That is a frankly ridiculous and immoral attitude. If you refuse to make minor accomodations when presented with choices that can reduce the amount of risk you cause others, you ARE responsible.
If you choose to dive drunk, you are responsible. If you choose to lie about the the status of your STD testing, you are responsible. If you actively discourage people from taking a safe vaccine, you are responsible. If you choose to go un-masked and unvaccinated when there is significant local spread, you are responsible. I don't beleive the best response to this is vilification or shamming, but that doesn't change the moral truth here.
If you have "hundreds of ways" we can make minor changes to save the lives of others lives, please share them because that sounds likr really useful information.
I think communication is best done with honesty and politeness and without censorship. That does not mean we absolve people of the responsibility of theor choices
The descent into authoritarianism is also a significant risk, but vaccine mandates are NOT that start of a slippery slope. They have been around for many decades and they haven't resulted in any slipping. If anything, getting people riled up about vaccines is a way to justify censorship and distract from the ever growing power of the surveillance state.
