if anybody from CHRISTIANITY or ISLAM goes against the Religious ideology and dont support their religion, they will be thrown out by the religious groups. Even after the death he wont be allowed to buried inthe allocated space and he wont be provided religious rituals.
But in HINDUISM, even after barking against hinduism throught the life, working against Hindism ideology and questioning the existance of hinduism, after death , nobody stops the rituals and functions after the death asper the hindu religion.
So you can have a rebel hindu not a rebel christian or rebel muslim. and this rebel hindus will add upto the vote bank of congress to beat Mr.Modi.
