I think Rojo's conclusion is correct but I think he made a really bad argument in getting there.
Not long ago the CDC claimed that vaccinated people didn't spread the virus:

However things changed fast these days and now vaccinated people apparently can spread the virus especially if they have symptoms (just like vaccinated people). Remember when Fauci said asymptomatic people are not the driver in spreading respiratory viruses:

No one knows what the future will hold for the virus. From how the UK looks right now it very well may be that the delta variant spreads just as easily from vaccinated as it does from the unvaccinated. If that is case then there is no reason for someone like Cole to get vaccinated, he would be risking a bad reaction to the vaccine like many other young healthy people have had.
I think what is really happening in this thread is you have one group who spent an entire year absolutely terrified of the virus. You have another group who didn't let it take over their lives and treated it like the flu (which is what it is for most people). Now the first group is pissed at the second group for not being as worried about it as they are. They want to feel justified in their extreme reaction to it. Just watch, pointing this out will make them even more crazed.
