Reliance or any other entity has as much a right to do business in any part of India as you or your cirlce of politicians have to breathe. The constitution guaratees your right to life...and it equally guarantees the right of others to conuduct business.
Further, have you ever thought about rights of the buyers - who in number far exceed the unorganized and inefficient (and also chearing oriented) small time retailers?
Are you not going to help your impoverished Tamil brethren in having a chance at buying with dignity...the same dignity that you preserve for yourself with your illegally obtained assets (houses, cars and foreign currency accounts in third party names).
Wishing you end of your career in disruptive, negative and illegal politics. Yes, both Tamil Nadu and the country do not need you!
