This caste,religion issues are pathetic are we not humans ? The only place where caste and religion is not questioned is in BARS and BROTHELS, nobody asks this question to the pwrson giving the drink or to the person offering her services. Wonder what the upper caste would do if they were dying of thirst and the only water on ofer was from the lower caste-would they drink it or prefer to die ? To progress we must forget all these petty issues nobody should prosper at the cost of another.
