Compared to Islam, Hinduism is much less of a threat. For one thing, it's basically limited to India and has no expansionist ambitions.
But the Hindu religion is not pretty. The caste system makes any of the western class systems, no matter how obnoxious, look tame by comparison. Hindu literature is fascinating, but I would not want to live under a Hindu regime.
The caste system isn't a part of the Hindu religion. It is a cultural issue.
I am sorry but your post is inaccurate. India has the largest affirmative action programs in the world. A religion that gave rise to pacifist movements like buddhism, jainism and that survived 800 years of islamic and i dare say christian aggression probably has some good points to it.
