Truth tends to offend when people can't accept it. They'll get over it. Or not. So what? She didn't say emphatically "Jesus was white" in the first place, but even if she had, she'd be essentially correct.
I watched it a few days ago, I recall she did say Jesus was white. Maybe I need to go back and watch again.
But you are wrong about it offending people because they can't accept it.
I grew up in N. Carolina, I remember seeing restrooms and restaurants that said things like "White Only".
My great-great Grandfather owned a plantation, he had slaves. When I was a boy, I knew the families that were descended from those slaves. Wonderful people, and God-fearing, much more so than most white folks if you must know.
I don't think the average white person knows what it is like to grow up and see everything good presented as "white" and everything evil presented as "black", but that is what black folks had to endure. They were told they were stupid, criminal, animals, the most horrible things you can call another human being.
And then to be told that God himself is white. What greater insult could there be? Why, if God is white, then surely the Devil is black.
How does the song go? Jesus loves the little children, all the children of the world, Be they yellow, black, or white, they are precious in his sight, Jesus loves the little children of the world...
It was a very stupid thing to say.
