even the members of legal advise forum are first human being then legal experts. You cannot expect them to helpsomeone to propagate against very instituttion of religion. If one has studied all the reliegions, he has rejected their teaching collectively then he is on to create a faith of his own like many heads of religious sects. He has a right to do so.
But even those persons who believe them to be atheists or call religion as opium for poor, when their family member dies they either burn or bury their body as per the practices prevelant in the faith to which they belong.
I again repeat. All re;ligions hve some common good teachings. [i.e. pious deeds, pious means of earning, charity, fasting, community service, equality before god, chastity in marriage, respect for society]. One just cannot avoid following these virtues.
