That's a generalization. That's like saying Christians love everybody. Hinduism in a lot of ways is like Judaism with an ethnocentric theology and caste system. I can't conceive of an orthodox Hindu believing that a non-Hindu has any role to play on earth other than being an extra, or that Christianity or any other religion has an equal validity to the vedas. I'm sure there are many Hindus in the world that are open-minded, but not because of any single incontrovertible command from a God. Try to be a non-Hindu dating a Hindu woman, and see quick the family will be to adopt the 'all paths are equal' nonsense.
American religion is becoming more universalist.
Well only a Hindu would say "Iswar, Allah Tere Naam" - God your names are Siva, Allah (I will add christ) - Bring peace to all. Can a Muslim or a christian say that?
Actually the Allah here is not the Allah of the religion of Islam but the Allah of Islam the faith. When man first looked up to the heavens and found God, he came up with a name for God, and as there are several languages, each came up with a different name. That was faith. But as time went by faith degenerated into religion - each with its own dogmas. I may be baised but by and large Hinduism is a faith and not a religion. Some dogmas have crept in obvioulsy, but by and large it is an inclusive faith not an exclusive one.
You use the word command from God - actually Hinduism is very different from yours - yours is a King Religion, God patterned after a King. Ours is a Teacher religion - God is our Guru, guiding us on the path to Moksha. A Teacher teaches, suggests and advices her students, never commands. We are responsible for our own fate, not God.
As for the caste system, it degenarated to its present form (as a muslim you can understand how a religion can be used for immoral purposes) mainly because of arranged marriages. Varna (not caste) was merely a occupation title - so a learned person was called a Brahmin, and a king or warrior was called a Kshatriya. A famous example is that of Sage Vishwamitra a Brahmin, was originally a King, a Kshatriya. Realizing the power of Knowledge the King left his kingdom and became a Brahmin. There was a free flow of people within varnas - but arranged marriages degraded the system to what it is today.
As for Hindus dating non-hindus, speaking as a Hindu, I would have a problem if my niece was dating a christian or muslim, others like Buddhist or Jain would be fine. The values are totally different for christians and muslims -first they will try to convert her even before marriage. Take a look at Sonia Gandhi. Can you imagine a Hindu woman marrying into a christian or muslim political family being allowed to remain a Hindu? Can you imagine that country giving the power of rule to a woman who is not of their religion? In Pakistan by rule one must be a muslim to be a President.
As I said, the values are totally different.
1. We don't teach fear of God - Our God is a Teacher not a King. Nothing to fear here.
2. We don't condemn others for not being a Hindu. Can you imagine the Buddha being born in europe or muslim lands being allowed to spread his faith? He would have been branded a heretic and burned to death! His teachings consigned to the fire to be lost forever! There would be no Buddhism today! Nor would they be a Sikhism, Jainism, Zoarashtrism nor the innumerable tribal religions (which are by the way under assult from christianity in India). No place of refuge for Bohras, Jews & Tibetans.
It is not a coincidence that until the modern age, western and muslim lands were barren except for one religion each, whereas Hindu India was and is a polyglot of hundreds of religions.
We don't want a mindset of my way or the Highway.
