They are treated fairly. The only person not being treated fairly are the Christians who are being told they must renounce the tenets of their faith, or be fined and possibly imprisoned.
Being denied the same services offered to straight couples because they're gay isn't being 'treated fairly'.

Says you. The PA laws of the states in question clearly mandate that anyone doing business with the public can't discriminate based on race, gender, sexual orientation, creed, religion, etc.
You say they can. You're obviously wrong.
Your entire argument has degenerated into you denying the law, denying PA laws exist, and insisting that religion grants you immunity to any law you disagree with.
It doesn't. So what else have you got?
