Murder is still an actual crime, one can apply reasonable limitations to any freedom. The issue is the ones you want are not reasonable.
Denial of service in a public accommodation is still a crime.
I guess what you consider "Reasonable" is at issue.
So let's review. Melissa Klein INVITED the couple in question to come to her shop if they ever decided to get married. It wasn't like this couple picked this shop out of a phone book or targetted it because they knew the owners were Christians. They were invited, and then found themselves being abused by Melissa's Bible thumping husband, who did like the thought of two ladies having sex unless it was on a porn tape, or something.
They made a complaint to the Oregon Civil Rights Bureau. At this point, the Kleins had the law explained to them and they could have simply apologized and that was the end of the matter. Instead they published the names of htis couple in right wing news sources, and they were subjected to even more abuse.
Just not working up a whole lot of sympathy for these people.
