Hinduism is all about caste system and other primitive beliefs. You westerners have no clue. Spend time reading Hindu scripture once.
"One day when the sage Atri was performing asceticism with his wife Anasuya, Brahma, Visnu and Siva came to him and offered him a boon. When Atri continued to meditate, the three gods went to Anasuya; Siva had his linga in his hand, Visnu was full of erotic feeling, and Brahma, beside himself with desire, said, 'Make love to me or I will die.' When she heard this coarse speech,Anasuya made no reply, for, although she feared the anger of the gods, she was true to her husband. But the three gods were overcome by delusion, and they raped her by force. Then she became angry, and she cursed Siva to be worshipped as a linga, Brahma to be worshipped as a head, and Visnu to be worshipped as feet, in order to ridicule them all, and she cursed them all to be reborn as her sons. Because of this, Siva was born as urvasas." --
