First, there is absolutely no way that “re-education against a person’s beliefs” is constitutional.
Second, even if the couple regularly allowed their barn to be used for weddings, that doesn’t mean they didn’t ALWAYS determine who could or could not use it based on other than dollars.
This is their HOME, and what they say about their HOME being a part of their religion is ABSOLUTELY true. It is a basic premise of Christianity.
So, this is different in that respect than a public business like a bakery. (Although, I think independent businesses have the right to offer whatever product they want to offer. If they don’t offer homosexual wedding cakes, then they don’t...same as if they don’t offer bages...they just don’t.
Let's look at it another way:
A lot of large landowners will rent their land for corporate events.
Let's say that a group wants to rent a farm for a shooting event similar to TexasCowboy Shoot that FReepers have each year, should a farmer who doesn't like firearms be fined for refusing to host such an event?
