If the vaccines decline as much as in the study in the article I referenced, vaccine herd immunity is a fantasy. If anything, the only way we can get to herd immunity is by not engaging in NPIs that postpone things (but that's assuming natural immunity is long lasting against all variants, which we aren't sure about yet either), that means that you are being selfish by trying to avoid the virus (since it prolongs all this for all of us), but that means there's not much we can do for people like poor Colin Powell (though the sooner we get there we might spare another Colin Powell equivalent 2 years down the line).
Back in my div school hanging out days, there was this nice evangelical guy who would hang out with us all. He was very tolerant of our arguments (ranging from the shockingly out right atheist even though it was the div school) to my weird theory about religion being like prisms (they all scattered some portion of truth). Very much a literalist, though, who did his best to convince us the Bible is the spoken word of God, and that the world was some 4000 years old. Even humored me on a tour of the natural history museum, which he angrily pushed aside as propaganda. Some time around Easter he blew up at us at a gathering in the lounge, saying we were incorigible and we were all going to hell, even though we were all overwhelmingly welcoming of his point of view.
It's not our side of the table which is trying to censor dialogue...we aren't the ones pulling tweets or facebook posts...we aren't the ones telling people they should just shut up and do as they are told....we aren't the ones telling people they are fing morons or c words. When this started, remember it was those of us on team reality who were in the minority. We've always welcomed your point of view which has always been constructive (unlike the 3 trolls), and your critiques have sharpened our own.
