So the Supreme Court is hearing the Colorado Cake case, and from what I'v read the media mislead and outright lied to the public on the details. It's a pretty clear case of free speech because the gay couple actually requested a custom cake decorated with gay pride symbols and messages that the baker disagreed with on religious grounds. The bake offered to provide them an already made wedding cake or to make a customized one without the gay pride symbols and they got pissed and sued.
So the baker was offering service to them and had in the past provided them baked goods knowing they were a gay couple. The baker is refusing to create art for a message his religion doesn't agree with and there is a pretty strong precedent to protect that.
The arguments used were awesome, a black carpenter can not be forced to provided cross's to a Klan meeting even if said carpenter provides those cross's to regular churches. A gay jewish painter can not be forced to paint swastikas for a neo-natzi celebration.
