Because it's phony.
Because Kanye West knows by now that, outside of his fanbase who'll defend him no matter what he does, he really fucked up with black people with all his Trump shit.
He's using Gospel as his Get-Out-Of-Being-A-Dumbass Free Card. Because outside of a few religious references, nothing in Kanye's life or music signals to me a proclivity to make a sincere (much less good) Gospel album.
But, to be fair, this ain't just Kanye. I got this same smoke for a good half of these "evangelists" using Christ for money and clout.
