So my question to you is why you are feeling so hurt about the hindu kids in California. Would you fight with same strength for the lower caste kids who are beaten in rural India if they ask for water. Did the communists create caste system? Why blame them everytime the caste system is highlighted. Blame game is played by all fanatics. Be it Hitler or Hindus. Isn't caste system is truth about Hinduism? Did not it inspire the Nazis? I definitely think you will hold a different view if you were a lower caste. But then who would like to resist or blame a system that put you on the top because of birth. Look deep inside you and you will find the bigotry and prejudice that you claim others have. My advice to you is that Hinduism is a bad relegion in its older format and its current format(the same old one) and hence if you feel ashamed you can change your relegion or start your own relegion.
