Equality, Shmequality

Rick Santorum had this to say a few days ago:

“Where do you think the concept of equality comes from?” Santorum said on the campaign trail last Friday (Jan. 20). “It doesn’t come from Islam. It doesn’t come from the East and Eastern religions. It comes from the God of Abraham, Isaac, and Jacob.”

This resulted in the mouthpiece of the Hindu American Foundation calling Santorum’s comments bigotry.

Now I am no fan of Santorum (link NSFW), but is equality really such an important concept in Hinduism? Do Dalits and Brahmins drink wine from the same cup? Do the Hindu religious texts and figures teach Brahmins and Shudras to marry each other?

Jains, Sikhs, Muslims and Buddhists were also outraged according to the article.

Does religion really teach equality of all? Seems to me that all these religious spokesmen doth protest too much. Their religions preach equality. Except when they don’t (which is often).
