All political parties are opportunistic and exploit caste or religion to some extent. At national scale, BJP looks most communal (but their communal intensity varies depending on forums they are speaking in. eg. read this). At regional scale there are many other parties which play identity politics eg. BSP :: Low caste votes.

What is wrong with identity politics ? For example, even 'Professionals Party of India' is appealing to the identity of 'professionals'.
Answer : What is wrong with identity politics is that it trumps debates on values, and policies. Voting for someone because s/he is a professional or muslim or hindu or low-caste, at the cost of another who may be advocating better policies and may be upholding better personal values, is what is wrong about identity politics. It divides us into class or blood based identities, rather than uniting us as a nation of equals, on the agenda of progress and development.
