Set that lunacy aside and instead focus on the fact that "Jesus routinely healed, fed and ministered to people whose personal lifestyle he likely disagreed with." Well then: what follows is that he disagreed with their lifestyle and treated them with basic human dignity. Jesus did not aid and abet the tax collectors in ripping off the poor. He did not miraculously make a condom out of dirt and give it to the prostitute telling her to be sure to practice safe sex next time. When he did not sentence the adulterous woman to stoning he did not condone adultery--rather he told her to "go and sin no more." Helping with the wedding arrangements for a gay "wedding" ceremony would be to help someone thought to be sinning in their sinning. It was a clear violation of the baker's conscience. And unless you think the Bible, Christian tradition, and pretty much every great philosopher and thinker in every major religious tradition in the history of the world are wrong (and instead go with your own or our society's feelings from like, 5 minutes ago), the man's conscience was correct.
Jim Crow Laws for Gays and Lesbians? Are you kidding me? Jim Crow laws were laws mandating racial segregation. The laws forced people to be segregated. Those laws were a disgrace. But so are the current laws mandating that businesses can't refuse service on grounds of sexual lifestyle. Just as the government has no legitimate authority to mandate racial segregation, the government has no legitimate authority to mandate that a business can't discriminate on the basis of religious convictions. Perhaps Christians would do well to go to jail, if they must, to wake our country from its dogmatic slumber.
