I only watched the first clip, all I saw was dancing. Am I missing something? I agree with the previous poster, there's nothing lascivious or idolatrous per se in the dancing clip, but knowing nothing about it that's all I can comment on.
As an aside: my sister recently married a man from India. My other sister's husband is a Lutheran pastor and he officiated. There were a couple of hundred people, most Christians.
At the wedding reception, the groom's mother called my sister behind a partition, and with two other Indian women forcibly placed a red dot on her forehead, draped a sari over her white gown, and tried to get her to wear ankle bracelets and bare her feet. My sister protested; she was asking repeatedly the meaning of the red dot on the forehead, and the ladies would offer no response other than "it is required". She did allow them to take a picture then promptly removed the jewelry, dot, and sari.
For a while, you could cut the tension in the air with a knife. Most of the middle eastern guests (and there were about 50) left early and didn't go to dinner with the rest of us. The mother in law seemed offended; my sister is the one who COULD have been deeply offended at being blindsided. Yet she tried cheerfully throughout the evening to include everyone and was especially thoughtful towards her mother in law.
*sigh*. Just ramblin'
