Which Sub Set Religion a man should follow?

A man can follow any subset religions of the Science superset religion. He can follow any of the subset religions like Hinduism, Christianity, Buddhism, Jainism, Islam or any other known religion in the world. Now a man’s religion is decided by his birth. A man should be given an option to follow any number of religions he likes to follow. Or he should be given option to follow no existing sub set religion also. If a man does not follow any subset religions of the world, then he is direct member of Science superset religion automatically. Even a man can take good things from each of the religion he comes to know. A man can follow multiple subset religions also simultaneously at the same time. We expect more religions to come in the world.
