No, in both cases. The point I was illustrating was that when you reach a point that the law can, for a perceived greater good, force people to violate their moral convictions, then ethical beliefs no longer can be a legal rationale for your actions, or lack thereof.
It may be a slippery-slope argument but I don't see anything in the history of our laws that suggests that the next slide down the slope, or even pure arbitrariness as ever been avoided for immediate political benefit.
I have to ask, what was the last slide?
Is there anything you consider immoral that you would not do that you could be force to do by law should someone decide that your morally is offensive?
Before answering your question, I have to point out your interesting choice of words. If you presuppose that the courts in the cases named above decided that the morality of those sued was offensive, then that is a very different conversation. The persons indicated in these suits, to my understanding, used their Christian faith as justification for withholding their services from gays and lesbians.
The courts held told that personal religious beliefs are not grounds for discrimination. Without having read the documents, and in the absence of actually being a lawyer myself, I can guarantee you those judgments did not say that Christian beliefs are offensive. The judgments probably said they weren't arguments. Because neither Christianity nor religion in general is on trial; although I understand it might feel like that to some religious people.
Essentially, in my narrow view of the universe, religious beliefs are opinions and are of no greater or lesser value than any other opinion. However precious they may be to the person who holds them, regardless of how many like-minded people there are who share these beliefs, they do not make that individual more precious socially or legally.
To answer your question, I will first qualify that I am not a religious person, and therefor am not subject to conflicts of faith and duty. Speaking as a citizen, there are plenty of things my government or the courts have done that I find objectionable, but I'm hard-pressed to think of anything I've been compelled or forbidden to do legally that causes me the sort of discomfort that people in the above court cases profess to feel.
Laws have expanded to include a previous disenfranchised minority -- your 'slippery slope' is my 'social evolution.'
