Christian conservatives feel aggrieved and they want to be heard. The problem is that their specific grievance—that everyone else hurts their feelings by not admitting we’re inferior—kind of sounds, well, hard to sympathize with. They need something snappier, a reason to claim that they are being oppressed by “anti-Christian bigotry”. The only problem with that is that in a majority Christian nation, most people are actually pretty accepting and even admiring of Christianity. Even if they disagree with right wing Christianity, they don’t do so because it’s Christian but because it’s conservative. Being a Christian is a privileged position in American society; that makes it really hard to claim you’re being oppressed.
