This may not be your view, but it is the view of many, that we are under attack, and people's lives are at stake. A ton of people have lost loved ones. Or they've had loved ones at deaths door and on oxygen and suffering for weeks.
So while you view those vaccinated folks who don't want to be around unvaccinated people as having a "religion," it may be just that they view you as a traitor to humanity. Back during the Iraq war, I didn't support us starting it, and for that position many people treated me far far worse than simply not wanting to be at a company picnic with them. The people who treated me poorly for my views often had family who were in the military, and didn't want to think that they were putting their lives at risk for nothing. It wasn't even that the US itself was at risk, it's that they wanted their family to be risking their lives for a cause everyone supported. So when people have been fighting against a local enemy that is hurting us all, I'm surprised the reaction is so mild as to not want to be at the same picnic.
what was their reasoning?
He did this contingent on the fact that I don't live near any elderly relatives nor do I socialize with anyone that is high risk. I don't socialize much at all really unless I'm outdoors.
I almost forgot to mention that he had looked at literature which stated that high antibody levels at time of vaccine could reduce its efficacy.
Frankly a lot of this is moving target so I'm keeping my mind open.
Although I fully agree that they should have a pass for people who already got it and have high antibody titers.
I caught it in mid-February with mild symptoms basically just loss of smell. I have very high antibodies and my physician actually recommended that I hold off on getting the vaccine.
Unfortunately, I have several co-workers who refuse to attend a picnic if I'm there. All of them are vaccinated which indicates to me that there is no logic and simply a demand that I adhere to the same religion they do.
Because honestly it's sure feels like a religion with these people.
