Nice quiz, but a small minor nitpick if I may: if the dominant religion is what you're after, shouldn't they be 'isms' or such (i.e. Buddhism, Judaism, Catholicism, Islam etc.)? No big deal, just thought I'd point it out ;)
I actually considered that but decided to go with the adjective forms just to have shorter words. I probably should change the description, so it lines up properly. Thanks!
