All kaikolars are concubines of brahmins. It fucking disgusting. they were so desperate that atleast one woman from every family became a devadasi. then her children come back and marry into the kaikolar caste. This is the classic definition of concubinage. Moreover some kaikolar pice of whore is yapping that kaikolar are not isai vellala it seems.
Go read the reference, isai vellala are kaikolar devadasis who then renamed themselves as isai vellala.
