Not if they want their business to make money. As it stands, refusing a potential good, reliable, and sustainable customer will cause the loss of income to any business. It goes against the teachings of Christ to condemn the lesser of our brothers and sisters, so using religion as a scape goat is unchristian. People forget that the physical is not judged by God, Jehovah, Allah, Great Spirit, etc. but the soul and what is in the heart of the individual that will be judged by our Creator. Good Luck to all who think otherwise.
