///Mainly, it is similar to jaywalking laws: it tells you what is allowed and forbidden, but it does not provide for surveillance and enforcement...nor could it.///

Rubbish. If you encounter it, you report it. There's no way to stop someone from driving drunk, no way to stop someone from breaking into your house. But having a law gives you teeth when you report it.

///Just as no one can stop people from crossing roads 'illegally', they cannot control specific examples of ignoring 'imposed prayer' rules and similar problems.///

Nonsense. You report it. It's YOUR job to report it if it offends you and the law is on your side. If you take it, you deserve it.   There's your surveillance--you. What do you want? Cameras and microphones planted everywhere to spy on everything to make no laws are broken? Do your duty as a citizen and report it. If your neighbor is revving his motorcycle at 11:30 at night and you can't sleep, don't expect the cops to magically arrive. You have to call them and complain.

///In some places...especially in the US Southern states, where fundamental Christianity is 90+%, the rules are routinely ignored, and the minorities who object are commonly harassed and/or pressured to say nothing....and kids can suffer a LOT from peer-pressure to follow the majority. When courts and police and state legislators don't like the 'rules', it requires a serious situation or a very brave individual to file suit or complain.///

And this is nonsense too. I've lived in the south. I have family down south and I still vacation there every year. Nonsense.
