This is basically the story of the Christian West since the mid-20th century. Welcome to the Gospel of Niceness. The 11th and most important commandment is Thou Shalt Be Nice. If you say mean-sounding things, that can't be Christian because Jesus never said mean things (except when he
did and
did and
did and
did,
ad nauseum). And so if the nice little neighborhood brown-people want to put some of their culture on your cathedral, why, it would be un-Christian to say No, because that would not be NICE. See?
