Indiana just instated the Religions Freedom Restoration Act (RFRA) which allows businesses to refuse service to anyone if they feel their religious rights are impeded by that service. Example: Not serving gays in a restaurant.
Sign found in Indiana.
It is aberrations like the Indiana law that make me realize again why religion has no business in politics and public life. Religion belongs behind closed doors. We should never allow religious preferences of some groups affect innocent citizens adversely.
