Just for the record, I am generaly considered a fundamentalist Christain. BUT, I disagree with the type folks you mentioned. I don't know where they are coming from.
Psalms 150:4 reads "Praise him with the timbrel & dance" also Psalm 149:3 "Let them praise his name in dance"
I could go on, but remember it wasn't that long ago the fiddle was called the "Devils Box".
To be sure, there are some dances I feel are indecent, just as there are some songs & gestures & such in the same vein, but some folks on both sides will never see the merit in their opposition's view. So I refuse to debate the issue. You can't change someones mind if they know it all.
