The tremendous backlash you talk about is also a myth.
In UP with its caste divides, the backlash was only by the Jats (who I think is 2-5% of the population). The rest of the Hindu community kept out of this and let the Jats fight it out.
UP with 80 Lok sabha seats will continue to send "secular" parties to our Parliament to decide our destiny.
You add Assam, Kashmir, West Bengal and Kerala to that "secular" list and we are truly Fcuked !
The reality is UP has to be won back by the "communal" forces. There is no alternative.
