I think Joni's thought there ("Roses Blue") was simply that ANY slavish devotion to a belief system which is exclusionary is not good - one could just as easily apply the concept to fundamentalist Christian or Muslim beliefs.

as in the Austin Lounge Lizards'"Jesus Loves Me But He Can't Stand You" -
(approximate lyrics)

"We're bringin' our kids up in a righteous way,
So don't you be bringin' your kids over to our house to play
Why, your kids'll grow up stoned, left-leaning, and gay
Jesus told me on the phone today"
