[The Cuban]

Racism is not an integral part of our religion, and never has been. The caste system is an integral part of hinduism.

[Gengis Khan]

Wrong.

Just as Racism isn't integral part of Christianity, but is nevertheless practiced by some Christians. The caste system is not an integral part of Hinduism but is practiced by some Hindus. Hinduism (the religion) neither approves nor encourages the practiced.

And I know more about Hinduism then you do.
