This was a ways back in the thread -- always a danger with mega-threads like this one, but could I just point out that these discussions can and DO make a difference to people? You strengthen raw steel by annealing it, which means you heat it up red hot, and then beat on it with a big hammer, rinse, repeat (literally), again and again. (I worked my way through college working in a sheet metal factory, and it stuck with me.) Same with ideas. Challenge and defense, done correctly (generally meaning with knowledge and respect), works wonders to identify areas of agreement and disagreement, and then to explore both.
Has it worked in this thread? Not always, but at least a few times important information has been successfully passed and minds have been changed. For example, Heppenheimer, a medical doctor and active poster, explained succinctly the actual immune process so that people could understand the multi-level nature of our immune systems and what that meant for vaccine effectiveness, then calmly answered specific questions without condemning the questioner, and basically halted weird posts in that area (at least until new people joined in without reading the earlier posts). As an experienced U.S. Supreme Court practitioner, I have done the same with Constitutional questions and the U.S. Supreme Court cases about vaccine and mask mandates and "rights." Those posts have basically stopped and I haven't had to do that since the the cruise line decision came down; even better, others have started posting their thoughts on new legal developments using the correct legal doctrines instead of blind, unsupported assumptions and media clickbait. For example, I didn't have to add anything to another poster's description of the effect of the recent rejection by Justice Amy Coney Barrett of the Emergency Petition for Supreme Court review filed in the Indiana University students challenge to a mask requirement, because that poster got it generally correct. There are others who have done the same in other areas. Annealing ideas works, and all of those participating in this thread have done that, to a greater or lesser degree.
Yes, it is annoying and tedious sometimes, and sometimes it flat-out doesn't work. But this thread has moved the ball forward, and provided significant new information and analysis. On Saturday, I cancelled a outdoor neighborhood potluck picnic that draws hundreds of people (and has been going on for 49 years) because our case count jumped by more than 10% in a WEEK and county health officials would have required us to check vaccination cards and require masks and social distancing. We are an all-volunteer organization, and, if we were to follow the health guidance we received, we could not have held the picnic without a stronger security presence than we were willing to provide. It was a painful decision that took over a week of debate to hammer out, but I was comforted, in part, by the information provided in this thread. And I thank all of those who have participated here, even those I disagreed with, to explore the issues that ultimately I had to deal with in the real world in real time.
