> different assessment of risks and/or have different risk tolerance

I could care less about their personal assessment of risk, what I care about is that they go on to put other people at risk through these shenanigans. Someone willing to go to a crowded church during a pandemic intersects highly with people willing to go into other public spaces during a pandemic. I don't want to be put at risk because of their stupidity. They're not just making decisions that effect themselves.

Someone could go to a church meeting in one state and get the virus and then give it to someone else who gives it to someone else who gives it to me. x1000. That is selfish. They aren’t giving a single thought for the potential ramifications of their actions on people they’ve never met. Acting in such a way that potentially many people could die, when all you would have had to do was stay home, is the very definition of selfishness.
