You simply don’t understand varieties of Christianity.
Some varieties insist that they must meet because of verses that say they must.
You can argue with their interpretations, but they are allowed in America to believe differently.
They believe that they must follow God in this. This is one of those instances when they must render to God the things that are God’s.
I think it is Matthew 18:20 “For where Two or Three gather in my name, there am I with them.”

It’s irrelevant to me what their religion tells them they “must do.” If they chance spreading the disease and endangering other people’s lives it’s both immoral and WRONG.
