Sounds like public accommodation discrimination to me.
However, it cuts the other way as well.
If you permit the bakers to refuse to bake the cake due to “sincerely held beliefs,” cannot that same “right to refuse service” also be extended to other classes of people like...say, cops and military?
Baker didn’t choose to become a cop whose job description calls for serving entire community. Apples and oranges question.
Is it the gym owner’s religious belief that law enforcement is an offense against God, or that soldiers are an abomination? Does his bible say so in those exact terms?
The bakers’resistance to queers is rooted in First Amendment “free exercise” principles. They’re religious at the core. This bigot can make no such claim, not with any degree of credibility.
