Well the broad "guidlines" that Hinduism is supposed to have ....is there in these "guidlines" any mention against Human Rights Violations? Occupying hundred thousands of people against their will? Regarding 200 million untouchables who are considered by Hindu priests as filthy and untouchable?
This has been discussed in a couple of other threads. Hindu religious texts do not encourage/condone/support casteism. The concept of "varna" has been misunderstood and twisted by people for their own selfish interests.
Let me give you an example that will be easier for you to understand - Islam does not ask Muslims to kill innocents (as far as I know). Why then are most terrorists Muslims, and more importantly why do they kill in the name of Islam ??
