Okay, I enter this with trepidation. I really didn't want to contribute anything to this, given how easily it could attract trolls, but I do want to put in my ten-cents worth, so please treat what I have to say with respect.
In regards to the 'hostility' he was treated with during the original trials, okay, if they believe he was so treated, then they can rule that way. I was not in the courtroom when the original trial was undertaken (or any of them, for that matter), so I can't really opine on that.
In regards to whether he had his freedom of speech or religion violated by being asked to make the cake...here's the thing: it is actually stated in the Christian bible (Romans 13:1-7) that they should obey the law, even when it directly contradicts their beliefs. (Note I said
their beliefs, not
the law of God; this is an important note of difference.) So he violated common law for his own personal beliefs, thus the court is justified in punishing him.
Were his beliefs sincere? Fair point of contention, and I have to say I don't think so. There are plenty of verses and stories
1 in the Bible about discrimination, and it would be hard for him to not notice these at some point. So no, I don't believe it was a sincere belief, as it made him discriminatory, even if towards just one group.
So, my opinion: a same-sex couple approached this baker to make them a wedding cake, he turned them down, citing his beliefs, knowing full well he was being discriminatory by doing so and thus violating God's law, and was brought to trial. The courts treated him hostilely, and they got burned as a result. Now, SCOTUS needs to make one more ruling: did he break the law? I hope they do make a ruling on that, and I hope it is in the affirmative.
1 I found a list of verses here, so feel free to browse it.
