Whether you say Potato or batata...it means the same thing that generates the third state of matter in your stomach. India has transformed well and thanks to education things are changing. But there are some guys who want to still use the old methods to gain popularity..and that is beat the dog...Brahmins. They are minority, they can't do anything and blame them for all the ills, you are in power.
Periyar or Periyarism should in principle be on the hit list of RSS. What periyar managed admirably is to force lot of Brahmins to convert to Christians.
