For some 'elders' ANY dance is unchristian.
I remember as a teen, my older sisters and mom rented a recreation hall, and invited JW friends to come for a night of dancing.
What dances? Old dances like The Virginia Reel, Polkas, and other early american dances - arm-length - and rigorous.
The folks that came all had fun. Unfortunately, one or two of the people who were there were elders, and reported to the 'big' elder who called my mom and sisters on the carpet - after they scheduled another dance night.
It seems that they read to her all sorts of 'rules' about being responsible for people who were there - afterwards. Or - perhaps they were outside - up to no good. Etc. They made her feel really bad, so she rented an off-duty sheriff to make sure that there was no one outside. No one was. The poor fella had nothing to do, so he came inside where everyone was - and pretty much had fun watching - and eating cookies - drinking sodas.
The 'elders' were not happy with this. They called her - and my sisters again. Had another meeting. Pretty much the same thing.
So - my mom and sisters did research in the WT publications - and sent a letter to Brooklyn asking if it was allowed - based upon 'insert quoted articles here'. Well, Brooklyn actually responded and pretty much affirmed that it was okay.
My mom called a meeting - inviting the 'elders' over to our house - where she presented them with this letter.
Ummm... 'elders' don't like it when you go over their heads, and they're called on the carpet... especially when it counters what they are saying. Needless to say, this 'big' elder wasn't happy with this.
Long story short - flashforward about 17 years. There is a 'wedding anniversary' for some older JW couple - and my JW wifey was invited (along with just about everyone else). I too was invited - even though I had already quit going to meetings - and was pretty much out by then.
At the party - it was nice, and there was a band ready to play music for dancing on the main floor. I saw this 'big' elder there - which kinda surprised me that he would have gone to something like this - since it clearly was going to have dancing.
I turned to my wife and said - "Look! See that fella?" She said, 'Yes...?" I said, "You watch him. When the music starts - he'll get up and leave."
Sure enough, later - when the music started - he - very stiffly - got up and mechanically headed for the door - leaving for the night.
Astonished, my wife turns to me and sez, "How did you know?" I shrugged, "Some people never change."
So... for some JWs - NO dance style is 'christian'.
