as a side not, yes I agreed and supported the cake shop's position.
The cake shop ruling was a separate issue because, since "designing and decorating" a cake is considered a "creative expression" then it cannot be "compelled". "Creative expression" in this case was considered "protected free-speech".
The cake shop apparently had no problem selling the gay couple an "off-the-shelf" pre-made cake.
They only refused to custom design one specifically for them.
The current expansion of "Religious Freedom" bills aim to cover things like "refusing to prepare a room for surgery" for a gay or transgendered person, or refusing to fix someone's sink, or refusing to sell them food at a restaurant. And like the hobby shop chain that wanted to offer a healthcare plan that excludes coverage for abortion (and presumably other medical procedures they disagree with).
If you want to claim a "religious objection" to something, it seems you should be able to point out a specific mandatory rule from your chosen holy text.
My position has always been, "If you want to pick and choose your customers, open a private club".
There is a distinct difference between a business that is open to the public and a private club.
