You're actually referring to the opposition (not the central government) that's alleged to be like that (mainly by the press). Anyway, almost all governments that come to power here try to pander to the minority groups in general (not Muslims in particular). Its what is basically called "vote-bank" politics here. Type that term in google, and you should see a wiki page regarding Indian politics. Namely this one: http://en.wikipedia.org/wiki/Caste_politics_in_India
