Hey, dude, you're the one who claimed the difference between objecting to the customer and objecting to the message isn't legally relevant 'because there are limits to “free speech”'. That's a non-sequitur. There is no valid argument form that takes you from "there are limits" to refusing to express the customer's message being beyond the limits to free speech. If I guessed wrong about which of the myriad invalid argument forms you were relying on to take you from your correct premise to your unsupported conclusion, then by all means, feel free to tell us which alternative invalid argument form you were relying on.
Nothing tribal about it. It's a consequence of their respective institutional roles. The CCRC is giving orders to the public, whereas the SCOTUS is giving orders to lower courts. That means the CCRC can rule any way it pleases, while the SCOTUS has to rule in a way it can explain, such that lower courts will be able to apply the SCOTUS's principles to future cases. Therefore the CCRC can easily have one rule for people who don't like pro-gay messages and a completely different rule for people who don't like anti-gay messages; in contrast, whatever the SCOTUS ends up deciding, it's going to be the same rule for everybody.
"...on at least three other occasions the
Civil Rights Division considered the refusal of bakers to
create cakes with images that conveyed disapproval of
same-sex marriage, along with religious text. Each time,
the Division found that the baker acted lawfully in refusing service.
...
The treatment of the conscience-based objections at
issue in these three cases contrasts with the Commission’s
treatment of Phillips’ objection. The Commission ruled
against Phillips in part on the theory that any message
the requested wedding cake would carry would be attributed
to the customer, not to the baker. Yet the Division did
not address this point in any of the other cases
with respect to the cakes depicting anti-gay marriage
symbolism. Additionally, the Division found no violation
of CADA in the other cases in part because each bakery
was willing to sell other products, including those depicting
Christian themes, to the prospective customers. But
the Commission dismissed Phillips’ willingness to sell
“birthday cakes, shower cakes, [and] cookies and brownies,”
App. 152, to gay and lesbian customers as irrelevant.
...
A principled rationale for the difference in treatment of
these two instances cannot be based on the government’s
own assessment of offensiveness. Just as “no official, high
or petty, can prescribe what shall be orthodox in politics,
nationalism, religion, or other matters of opinion,” West
Virginia Bd. of Ed. v. Barnette, 319 U. S. 624, 642 (1943),
it is not, as the Court has repeatedly held, the role of the
State or its officials to prescribe what shall be offensive. ..."
