Because, over and over, religious gatherings caused spread of the virus.
Some people are extremely upset about this, but, it's not everyone. It's mainly upsetting the kind of people who go to church, and like having a weekly social/philosophical community experience. That isn't everyone.
People were extremely upset that bars were shut, as well. That's because the kind of people who go to bars, also like to get together and socialize.
The other big spreader events were parties, and crowded workplaces.
It's not about stopping religion -- it's about curtailing gatherings where people talk, close to each other.
