I can't imagine what would happen if anyone tried to pray at a sporting event here. Probably booing.
Definitely no praying at group activities or meals that aren't in a church setting.
I really can't imagine it.
I've only read to this point (page 4) of the thread, but wanted to pop in with my observation of the social aspects of belonging to a religion.
There are a lot of places I've been in the U.S. and known a lot of people for whom religion plays a huge role in their social life.
I can remember over 40 years ago, when my maternal grandmother was alive. She lived in Newark NJ. All her life the Catholic church played a key role not just in her religious beliefs, but who here friends were, what she did socially, and who she turned to for fun or interesting things to do, or to watch the kids.
From what I understand, she went to church daily all her life. So did most of the women she shared her childrearing years with. In her old age she and the other ladies still attended Mass each morning at 7am. If one of them didn't show up for church, afterwards they would all troop over, en masse, to the missing babcia's apartment to see if she was all right.
The person who was feeling sick, or had fallen or whatever was confident that if she could just hold on until after 7:30, she'd have plenty of help.
Fast forward to today. Someone I worked with a couple/three years ago is a great example. She was a young woman, maybe 25-26. While working together she started up with a young man, and it was apparent they were for each other, and that it was leading toward marriage and family. One day we were talking about where they were thinking of settling down for their home, and she was sharing her ideas. One of them was that she'd need to get involved in a church by the time she had her first kid. While she never came across as particularly religious, (she stated she believed in God, but didn't think about it much at all.) didn't go to any church, or never mentioned it, she firmly believed she needed to belong to one to start a family. Why? Because she felt it was important to take advantage of the social opportunities and connections that would be available for her, her husband and kids over their formative years.
All I have to do around here is go into a craft store, small or a big chain like Hobby Lobby or Garden Ridge, and see the huge selection of christian related arts and crafts items to realize there's gaggles of women all over gathering to sip ice tea, gossip and put together bible related scrap books.
