The ones who enthusiastically took their kids out to get vaxxed are already a write‐off.
I feel bad for the kids. My parents made some good choices and some shit choices and I get to live with them. No one is perfect, but if you had a brain in your head and did even a hour of research you would likely not have allowed your kid to take the mRNA vax.
I had a co-worker that said basically "But he wants to play sports". I told him, take a couple of years off and still train and start reading more. He is not going to be a sports star, he probably won't care after a couple of years anyway and will probably go on to a very good career. Now he might be dead before he is 35 because you let him get the shot because he wanted to play football.
