I want to discuss with you two issues you are raising here. One is so called secular politics and the other is politics of Congress party.
What does secularism mean? Dictionary definition says that secularism is the view that religious considerations should be excluded from civil affairs or public education. Secularism itself doesn't make sense for a nation like India which has religious history of more than 9500 years, has a vibrant social fabric based on religious mores, and founded on religious ground (2 nation theory based on religion). Even if we agree with so called definition of secularism, it still is not practiced as is in India. Congress feels comfortable aligning itself with so called communal party Muslim League in Kerala, castiest party RJD in Bihar, but feels uncomfortable working with BJP. If BJP's nationalism based on religious aspiration is wrong, then Laloo, Mulayam, Mayavati, Sonia's caste politics is wrong too. Both are based on social divisions based on caste, color or creed.
Congress politics is wrong from the start, It accepted two nation theory based on religion but negated religion in polity. It didn't create a viable opposition in earl
