Should a business be able to deny service to a customer if the request conflicts with the owner’s religious beliefs?

In 1993 the federal government passed the federal Religious Freedom Restoration Act. The law was intended to protect Native Americans in danger of losing their jobs because of religious ceremonies that involved the illegal drug peyote. Since then 20 states have passed their own versions of the “religious freedom” laws and 12 more have introduced the legislation this year. Supporters of the law argue that the government shouldn't force religious businesses and churches to serve customers who participate in lifestyles contrary to their owners’ beliefs. Proponents of the law argue that the political context has changed since 1992 and states are now passing their own versions of the law with the intent of discriminating against gay and lesbian couples.
