Why would a believer in either be willing to compromise their faith?
I propose the athian religion. Where for four days of the week you believe in god, and The other three days you spend your time telling people there isn't one.
Sounds ridiculous I know. But all it is is a combination of belief systems. Just like Christlam!
Christlam... Outrageous.
I'll support any Christian who wants to fight this absurd notion.
