Claiming the benefits outweigh the side effects is a blanket and unsubstantiated claim that has nothing to do with the science. Because the science has completely failed to quantify the degree and severity of the side effects.
To the contrary it has ignored and covered it up. Again, find me the controlled clinical long term trials of vaccinated vs unvaccinated. If you make broad, declarative claims you need to back it up. You can’t just lean in “a bunch of people say this” as evidence.
