Obviously, things that can be known, and can't be "fluid" should demand greater protection than those that cannot be.
You admit/acknowledge too that if the couple was simple a hetero black couple or hetero mixed-race couple and the baker said "we don't bake wedding cakes where blacks are involved", this decision would've been very very different. Even the LGBT payroll bloggers won't touch that one because they know. They know the Court just made the distinction once and for all that LGBT is behavioral and not innate. That was a HUGE blow to them because they have been ramrodding all their judicial-legislation through so far by convincing the judges and Justices that LGBT is innate.
This is the false premise and why Obergefell is so fucked up and wrong. People of the 50 states cannot be forced to condone a repugnant lifestyle (while other equally-repugnant lifestyles arbitrarily have no privileges or protections from the majority). And this case was just the tip of that "oopsies" mistake being found unworkable. This time in a test against faith of a Christian. But more tests will come.
For instance I am basically a secular agnostic. But I have VERY strong convictions against a lifestyle that parades graphic acts of deviant sex in public "in pride" (defiance) where they welcome and hope children will be watching and even marching with them. My rights to refuse to condone, participate in or promote such a lifestyle will have to be protected too. You cannot be FORCED to play along with known child sex offenders. And yes, that's what anyone who supports such a parade or participates in such a parade, or brings their children (!) to such a parade to watch are: child sex offenders in the purest and truest legal sense of the definition.
Don't believe me? Go pull your pants down just outside a schoolyard at recess and have another guy mock butt-ram you in front of the kids and see how fast the cops are there to slap the cuffs on you. Do that in front of the same schoolkids on a field trip on the sidelines waving rainbow flags "supporting gay rights!" and not a thing will happen to you. Odd, don't you think? But for me I don't see the distinction. And those are MY deeply held convictions about protection of children. Try to take those from me by force and I'll see your ass in court.
Obergefell: "Oh what a tangled web they spun when with a false premise they had begun"...
