"A few years back when TN was ruled with a iron hand by a brahmin CM, dalits in TN were forced to drink urine & eat human faeces(shit man!)of the upper castes because they drank tea from the tumbler used by upper castes in the tea shop"
Can you give some more information regarding this incident(a link to the news item etc. )? To which caste do the above mentioned 'upper castes' belong to(the ones who committed the crime) ?
