To pull a quote from the article, "The cabaret law itself is absurd. It's totalitarian. Two years ago the only places it was illegal to dance were Manhattan and Afghanistan. And now you can dance in Afghanistan..."
Personally, I think the right to gather and dance is pretty fundamental, up there with free speech and assembly - it's a communal experience that, at its best, is transcendent and spiritual. But the dancing community has come under attack a lot from government lately.
And as Emma Goldman famously said, "If I can't dance, I don't want to be a part of your revolution."
