manusmirti was written by manu whose 3 sons were ksherikas out of total seven as they themselve did not follow,who will follow now.christians follow this practice in india.see villupuram church,priest closed the church becouse it was visited by lower caste people.christianity is still worst follower in casteism.only new converts like you consider manusmriti as your bible.hindus do not read but read only bagwat geeta and ramayana.
