Actually, it's about compelled speech...which has actual protection under the First Amendment.
And T.Lex...c'mon, that dissent was nothing great. It was basically: "I disagree".
As usual, I thing Justice Thomas was dead on.
Well, my personal philosophy aligns closer to Thomas. (Who has been rumored to be catatonic or otherwise distracted during oral arguments himself.)
But, Ginsburg presented a different take on the case that I found... sympathetic ... might be the best description. That is, more behavior-oriented, and thus amenable to regulation, than the majority opinion.
For instance, what if the dude wanted a traditional cake, that said nothing on it. Not even a cake-topper made of soap (with a protective finish). Then, what exactly would be baker have a problem with? I personally don't agree with the following equivalence, but if we accept that the baker could not refuse to bake a cake because the couple was Jewish (or some other protected class) based on his religion, then we've already accepted the paradigm Ginsburg proposes. It is then up to the locale to determine what protected groups are protected.
She also deconstructed the examples propounded by the majority for instances where the commission declined to act. Moreover, it sets up a situation where a commission can't re-visit past precedent, which is awkward.
Ginsburg is a solid jurist. One that I rarely align with, but that's ok.
