It's too funny, my old pastor before I moved hated Chevy and would preach against them. Threaten to kick you out of church for driving one or just ask you to park down the street, so nobody would know you were a member there. Joking of course, but it was hilarious!
My present pastor hates Fords. He will call people backslidden or unsaved for having any involvement with a Ford. You should hear the Amens when that happens! Same with the Raiders. We know you can't be saved and be a Raider fan. Gods people are 49er fans, everyone knows that! C'mon!
