Majority in parliament are hindus but they are divided into sub-sub-caste communals who support to appease the minorities. Congress, Samajwadi, RJD, BSP, JDS(S) and so on... are all caste-based communal parties. They talk about the caste/religion whenever they are in need to appease. We can only blame the system and the people behind its wheel. It is like, when the Police & Robber are the same party.
