Don't peddle some political snake oil here dear. Nobody has a birthright to pray to the God. Similarly nobody has the birthright to be a priest. If some existing temple does not allow you inside, force your way in. If some existing temple does not allow you to be a priest, erect your own. The progressive among the Hindus will support you whole-heartedly.
And as far as reservation for the OBCs goes, it is a case of seer opportunism. The OBCs are no more downtrodden than many of their so called upper caste counterparts. It is just that easy money is just too lucrative to resist.
