Based on experience with my own church, there are alot of old people who likely grew up believing the news and trusting the government, so they actually believe a deadly virus is out there. So despite there being no repercussions for holding services, they'll still choose to 'be safe'.

I've wondered, too, how long people will choose to wear masks in the future. I'm sure that some people are now permanently paranoid of standing near another human...which is probably what the demoncrats wanted.
