This is a good decision taken by the TN Goverment. As per Sachar Commiyty report the indian Minority, mainly Muslims are very bad position than the SC/ST at some of the states.
Pls note, reservation is not a favour it is a rights allowing by the constitution to the backward community. that is a opportunity to come to the main stream for Backward comminity and minority.
Indian Minorities are not imported,90% of them are converted. The reason was the bad customs from the Hindu religion in ancient days.
