No, but we should be free to do so without repercussion. If you don't like it, move on. It's simple.
This new age "Separation of Church and State" garbage is my MAIN concern. A REALLY big issue for us all. It has to be corrected, yet no politician speaks for us. Should we vote for anyone just to please others? Or just let it ride?
Well, I'll put you down as "wanting to be able to do whatever I want to whenever I want to without repercussion."
Just remember: if YOU get to do whatever you want, so will everybody else.
So, tell me, how are you going to feel when two guys have sex in front of your kids at the library?
It seems to me that your group must be praying in a way that interferes with the public if you have been stopped or told to move along. So long as you use a bit of common sense and courtesy of others, I see no reason why your group would not be allowed to pray in public places.
That means, don't create a scene or block the passageway of others or loiter for an extended period of time.
If a group decides to pray in a public place and they do so in conversational tones and don't block the paths of other citizens, you'll be just fine.
Now, if you scream your prayers and have your group block the path of citizens, then you're in the wrong. Any group screaming in a public place or blocking the public from passing, whether they're praying or doing anything else, would be in the wrong. I suspect that it's not the act of praying that got you in trouble; but your behavior in the way that you went about it.
If you are arrested for praying in a way that is courteous to people who are not part of your group, then you have good grounds for a lawsuit.
