Religious is almost certainly Arkansas, given that they have Black people.
Good Lord. You think Southern whites are all non-religious!!!
Compared to blacks, yes.
Where the hell do you live? You're insinuating white people in Mississippi are no more religious than white people in Massachusetts!
No, he meant that compared to southern blacks, southern whites are less religious. He's not comparing white people in different regions. He's implying (I'm assuming) that because there are more blacks in AR than in WV and that southern blacks are more likely to go to church than southern whites, thus AR is more religious than WV.
