All have equal rights to follow the principles that adhere to. This is how a nation should be. One takes religion and caste when one feels insecure and incompetent.
Religion is a faith. No infant is born with a particular faith. We are all humans first. The faith brings order in this apparently chaotic world, and brings meaning to life. Beware of the priests who divert this objective of religion. Religious principles have always been bent and twisted to the advantage of this class of people.
Any intolerence will lead to deaths. History is replete with examples. No one benefits. No one. Germans thought they could get mob support by anti-Jewish sentiments. But look what happened to Germany by the end of the war - destroyed, its women jumping into rivers to commit suicide. It's the kind of horrors communalism could bring to this country.
Any party that talks about religion need to be abhorred by people. They should have no place in the modern world.
It is said that every form of government degenerates into something undesirable. Democracy could degenerate into mob rule, unless we all take steps in time.
