Anyone want to bet on this horse race?
To me, this kind of story is a cultural issue, not a legal issue.
Unless there is something unconstitutional or indefensible about PA laws - and I doubt there is - it's hard to imagine the Kleins have much of a case.
If this was indeed some kind of setup, well, it was a legal one. That's where the cultural issue comes in. If the lesbian couple did this to punish the Kleins and make an example out of them to intimidate others - and that wouldn't be the least bit surprising - that's more a reflection of where we are as a society. They'd rather punish the Kleins through the legal system than just get the cake from someone who wants to sell it to them.
The fact that the lesbians' supporters choose to ignore is that the couple CHOSE to leverage the law, they were not FORCED to. They could have just walked away, and it would have just been over.
This is just a small symptom of a much deeper issue.
