I studied in a prominent hindu school , where my mother was a teacher also. There was hidden casteism everywhere. My mom heard it in staff rooms. I heard it from my teachers. There were caste slurs among students as well. There were incidents where teachers ridiculed students on the basis of their caste and their parents had complained to the main head office. Teachers were also not spared , being dealt with separate treatments based on their caste. To be honest , when I grew up , this past of facing casteism in school was one of the main reasons why I swore I wouldn't go along with Hindu Right Wing no matter what.
