This forum has seen a lot of it over the last three years. The country has seen quite a bit of it, and the world at large has seen a lot of it.
All such movements started with a bogey. For Nazis it was the Jews and then the bogey of the treaty ending WWI.
Closer home, Pakistan uses the bogey of a "Hindu" India.
In India, right wing extremists use the bogey of Muslims and "appeasement" of Muslims for their rise.
The difference between the Nazis and Pakis on one hand and India on the other is that the former used/uses foreign bogeys for their form of extremism with Nazis detesting the treaty of Versailles and Pakis using India but on the other hand, Indian extremists that have come around sadly use their own countrymen as bogeys.
That is certainly dangerous for the country. Nazis were able to rise because they wanted to get back at the rest of the west but Indian extremists have risen against their own countrymen fed by all kinds of propaganda. Chain reaction is always the result of extremism.
Indian extremists are showing the same kind of behavior as one detests among Pakis. I guess at the end of the day, all extremists are the same. Unfortunately it's going to harm the country.
