Except you didn't know that back when. And frankly, you don't know that now either, save for one key fact:
It is only because of demagoguery that you can assert the above; such demagoguery has singularly destroyed any possibility of finding alternative solutions, possibly even safer solutions, and possibly even more effective solutions than the ones the demagogues have sold us as "the single best weapon against the pandemic."
And why? Because too many accepted as gospel, with absolute, utterly blind faith in the demagogues, that the vaccines were the only solution.
So yeah, now we're "stuck" with vaccines of questionable safety, questionable effectiveness, and questionable prevention against transmissibility.
But hey, they might lessen issues with the virus. Whoop.
Again, you can't say that with certainty either - not when the possibility exists for ANYONE, unvaccinated or vaccinated to spread the virus.
I don't have the moral right? I'm vaccinated, friend. Apparently you are too. What gives you the "moral right" to judge me - or anyone else for that matter? On what authority does your "moral right" trump mine, or anyone elses?
