Cross an African with a Chinese and you get an Indian? Still believable, I believe. Not as dumb as few population genetics morons' interpretation that you should in fact cross European male and Chinese female.
It seems in the above spoof those non-Indian girls are atheists (I guess non-religious is euphemism for atheism). But the Indian girl is "actually" a Hindu. Now that is a problem. There are atheist Hindus who are generally communals or castiests. The regular atheists do not identify with their religion of birth. I am positive that a Hindu atheist when asked to be part of that video would have angrily said, "Why it has to be a Hindu. We are an easy prey. Aren't we? Try to get a Muslim girl and do your spoof".
That being the case, I am sure that that is a believer Hindu. A believer Hindu taking part in a parody of Christians by atheists only goes on to show she is intellectually challenged. That is not a sin. At least in Indian context believers are normal people and atheists are abnormals. So I have nothing against her.
The problem is what those light skinned atheists were thinking when they asked a believer to be part of that video. They should have selected an atheist Indian girl. They must have thought dark skinned intellectually challenged Hindu is beyond mockery. I am afraid that smacks of racism.
