A person is born in a family, not by his own choice. That family has a particular religion and that becomes his religion also, again not by his own choice. In olden days the matter ended there. He had to accept that religion as naturally, as he had to accept his parents, but today the situation is different.
The youth of today is enlightened by education and is imbued with the spirit of freedom of thought, which is the hall-mark of the modern age. He wants to satisfy his intellect before accepting any idea as a truth.
