The majority I talk to believe it's a push towards the mark not that it is the mark, because there is obviously no mark.This is an ideal example of the distinct line between what's interpreted as "reasonable" with respect to what the law is around religious accomodations. Personally, I think this is an unreasonable belief. But if I were the person deciding whether to grant the accommodation, my own belief doesn't matter. The "reasonable" test doesn't mean that employers get to judge someone's religious beliefs as "unreasonable". If that were the case Jetta, in a position of such power, could always deny any religious request for accommodation if it wasn't what he believes.
It's not up to an employer to judge a religious belief. They can judge whether the belief is religious in nature, is sincerely held, and that the requested accommodation is reasonable. So yes, if you sincerely believe that getting the vaccine is the mark of the beast, I think a religious accommodation should be granted for that.
Some however believe it is the mark completely. Not many I have talked to but a few.
I'm sure there are many others around the United States that feel similar to that as well.
I believe the Navy Seals that filed religion exemption filed based on the body is the temple of God and they must choose what is allowed to enter the body/temple and they feel the covid vaccines are not good for the body/temple.
Like you said you may not agree with anyone's religion or their personal religous beliefs, but must respect others beliefs. Unless of course it involves taking human life....
