Youb have erred in interpreting the Karma theory. The theory propounds that a person doing sins will have to bear it whether in this birth or the next one. It nowhere mentions that a person doing sins will be born as mochi in the next birth!!People who are dalits shuld feel proud in calling themselves dalit, just like sardarjis dont object to offensive jokes, nor do marwadis when anyone miser is referred to as marwadi!!
