Caste System is not just decided by Brahmins .It is the Social System, whether right or not . Dear Sir /Madam , please self introspect yourselves . I do not know which Caste or Religion you belong to . All are humans. There is only one Religion called 'God's Religion ',. People will have different faiths / Religions , but God can not be two.God is only one , called by different by names , worshipped /loved / prayed in different paths /ways .
But,please think of your ownselves and family . How, many Brides /Bridegrooms of your Family have got married to people of different Castes / Religions ?.
Change ,should start from ndividuals ,families, neighbourhoods,villages,towns,cities ,states , countries and finally the world .
Do you think Brahmins had been to other Countries and created Shias and Sunnis among Muslims , Catholics and Protestants among Christians , White and Black (Nigros ),Poor and Rich ???????
Please ask these questions among yourselves and then you will find better Answer ,I suupose and pray .
