If this is the only fact, than it's a pity why people fight to death against inter-caste marriges... and that's even geography related castes (like Gujrati, Tamil..)
But that link does not specify any thing related to whether Hinduism is against inter-caste marriges or not..
& if hinduism is against than there are alot of cases in which inter-caste marriges were supported by renowned Hindu Pandits. and as much as i know these casts are treated as one of the twenty-six Gunas that are matched before marrige.
if we could enlighten this than it will make many lives easier including mine. Kindly include your individual views on inter-caste marriges.
