There was no conflict for the owner of the Masterpiece Cakeshop until the State decided to change the definition of marriage.
Actually, the change was thatvthe courts striking down an illegal law. Do you think that the State should be allowed to have illegal laws?
Meaning, any and all homosexual customers where having all of their requests met and no one's religious convictions were being violated.
Then, all of a sudden, the State (politicians and judges) made a decision that potentially placed this, and other, business owners into situations where their religious convictions could be violated.
Judicial decisions are a bit of a blunt instrument. All they can do is strike down unjust laws; they can't really craft new laws.
If the federal legislature had been more on the ball, they could have arranged a more gradual change for businesses. Blame conservative legislators for blocking attempts to do this and insisting that an illegal law should stay on the books. They could have dealt with it, but they didn't, so the courts got involved.
Of course, it would be ridiculous for businesses to expect that laws will never change. Factories that were built decades ago still have to have modern pollution controls, even though this cost might never have been considered when the factory was built. Lunch counters that were established during segregation now have to serve people of all races, regardless of the opinions of the owner. The same holds here.
If that were not bad enough, then the State claimed that they would need to violate their religious belief or lose their livelihood.
No one should be forced to make that decision.
That's hardly the decision in question. If their bigotry wouldn't allow them to sell a wedding cake to a same-sex couple, they could always sell other baked goods besides wedding cakes.
If they did decide to close the bakery, I have no doubt that they'd be able to find other employment to preserve their livelihood.
This is no different, in my opinion, than the State making a law respecting the establishment of a religion.
If your thinking is that muddled on this issue, then you have my sympathies. I wish you a quick recovery for whatever impairment you're suffering from.
