Not it isn't. There are many instances throughout the jurisprudence history of this country where the Court has had to deal with conflicting rights. Why do you believe the civil rights legislation of the 50's-60's to be "bad law".
There is no "Constitutional crisis" in disallowing people to use their religion as a ploy to do that which the Constitution and anti-discrimination laws prohibit. Religion was never meant to be used as a means to get around the law.
Civil Rights legislation wasn't bad law, but the perverted interpretations through judges who have lost their footing on basic first principles of the Constitution has produce bad precedence. They are engaged in government mandated morality. When a court of law can “prohibit” the free exercise of your religion (and that includes your religious beliefs), the government has just violated the First Amendment. In essence, the government has taken away your right to choose your belief system and forced you to comply with the belief system of the government’s choosing or another individual. This becomes inequity of the law when one belief system is held in more high regard than another. We've talked a lot about the cake decorator that was ordered by the Colorado judge to “cease and desist” from "same-sex couple discrimination" even though what the judge ruling did was force the baker either violate his conscience and not practice his beliefs and bake the cakes for gays or stop baking wedding cakes which means he won't be able to support his family. This is reprehensible especially when the judge cited "hurt feelings" of the gay couple in determining his ruling. How much longer will it be before we see doctors drug into court because they refuse to do an abortion because it is against their moral conscience? Or how long will it be before groups like GLAAD through their bullying tactics will be able to drag a priest, rabbi, minister or any other religious leadership that teaches homosexuality is a sin claim discrimination/defamation at the pulpit and be successful? There's a reason legislation has already been proposed in the House with many sponsors that will stop this inequality of the law. It won't go anywhere while Harry Reid is still over the Senate and Obama is in the White House but some day it will be passed.
