Chic, here is part of the Snopes analysis you so eagerly jumped on:
Biden: “If you’re vaccinated, even if you do ‘catch the virus,’ quote, unquote, like people talk about it in normal terms, you’re — not many people do. If you do, you’re not likely to get sick. You’re probably going to be symptomless. You’re not going to be in a position where your life is in danger.”
So he was "swearing," "promising," etc. that if you're vaccinated you won't get it? Obviously, Snopes is saying the opposite.
He does have a kind of goofy way of speaking; so what? Try listening to what he is really saying, instead of nitpicking his rhetoric to death. And the word "death" is sadly appropriate here; that is what happens overwhelmingly to unvaccinated people who get Covid (compared to those who are vaccinated). And they are helping to spread the disease to everyone else, causing untold suffering, putting the brakes on the economy, closing schools, forcing cancellations of all kinds of plans, and in one way or another, harming everyone. Even those who have been vaccinated are being harmed by those who are stubbornly holding out.
(I know some people can't get the vaccine for medical reasons, and I do feel sorry for them.)
