The religion that is afraid of science dishonors God and commits suicide. Every influx of atheism, of skepticism, is thus made useful as a mercury pill assaulting and removing a diseased religion, and making way for truth.
If everyone will try to understand the core of his own religion and adhere to it, and will not allow false teachers to dictate to him, there will be no room left for quarrelling.
I have come to the conclusion that whether or not a person is a religious believer does not matter. Far more important is that they be a good human being.
