I completely agree with you. Surely the religion should be the matter of individual choice. But the problem occurs when the majority especially the fundamentalists of so-called majority start dictating you. They impose their fait in you and bury yours. We are especially concerned about the communal fascism. See how the communal fascism operates, Mr. Narendra Modi demolished 268 Temples out of 398 Temples in Gandhinagar of Gujarat by bulldozing these but you don't see any hue and cry except a few small Nawtanki of VHP in Gandhinagar. Imagine if someone else would have done this, I'm sure there would have been a riot nation wide or at least hatred campaign would have been imposed in the country.
Secondly, the right wing was always coining that all the Muslims are terrorists and Christians are Naxalites. Yesterday, I heard Mr. Sudarshan Chief of RSS saying that there is no religion of terrorists. See how they suddenly take u tern when their involvement in terrorism was unearthed. Therefore the role of people like you and me are huge now. At the moment, we must work towards protection of our secular democratic beloved country, where everyone can enjoy their rights and privileges including the freedom of religion guaranteed by the Constitution of India.
