People are more than free to do what they want where they want (as long as those who are in charge say it is OK). If I thought that singing and dancing during church services were appropriate, I'd probably go to them. I've been to a couple of such services. I didn't like them because the focus was on the person doing the dancing and wailing, not on God.
Don't you mean *your* focus was on them?
Fair answer - thanks!
