Well, the way I see it is that there are consequences for breaking the law, including anti-discrimination laws. There can even be severe consequences for breaking the law and that includes anti-discrimination laws. Despite what seems to be a popular belief among conservative Christian circles, Christians living in America are not above the laws of this country and they aren't entitled to discriminate at will against homosexuals (LGBT) or anyone else they might find unfavorable or whose lifestyle they may disagree with religiously. If some Christians are willing to violate anti-discrimination laws because of their religious convictions then they should be willing to accept the legal consequences of their actions. Christians should also be held accountable for breaking laws, including anti-discrimination laws.
Anti-discrimination laws were put in place for a reason to protect LGBT people and other marginalized groups of people from being discriminated against in this country. LGBT people don't deserve to be discriminated against or held with contempt because of their sexual orientation. And if Christians own a public business (that normally accommodates the public as it should), but find themselves unable to accommodate homosexuals (LGBT) because it conflicts with their conscience and religious beliefs, then they should seek some other kind of private or religious occupation instead.
