I believe it shouldn't be. My perception of the different religions out there is that they provide us with a choice in faith so that we, mankind as a whole, can continue to personalize our own unique identities. Despite whether our free will was given to us or is manifested by how our neurons react, it is a characteristic of mankind and we exercise that ability. Respect others opinions and perceptions of life. You don't have to totally agree and believe in it, but simply understand and accept ones faith. We all have faith in something.
