Your argument is called a "Slippery Slope".
Change his color, then hey maybe it wasn't a virgin birth. I don't care! Hey maybe he got married. I don't care! Oh and he wasn't really a Jew. Hey, I don't care! And he hung out with 12 men so he was gay! Well we need to love them as God's children so I don't care! Oh and he wasn't the real son of God! "Hey he taught important things I don't care."
What makes the first item on your list from all of the rest of them is that the color of his skin has no bearing on who He was, what He did, or what the Bible says about Him. All of your other "examples", including making him female, do. That's a very easy line to draw.
You nonchalant attitude towards the true Christ is what eventually demeans him.
Any more than your rigid attitude toward Him? Do you know for certain what Jesus looked like?
He can't be all races to all people just because they feel through their skin tone or race they are nothing without their version of him. They are not listening to the word, thats why they change him so they can accept him in their world, not caring about being accepted in his through his word!
As I said way back at the beginning, I think needing a black Jesus kinda misses the point. But God doesn't have a race and the race of His Son was an incidental accident of the ethnicity into which he was born, not an integral element of who He was. If depicting Jesus as a black man helps a black person better feel that Jesus is his Savior, too, then I don't have a problem with that. I would have a problem with a black person depicting Jesus as black for the purpose of claiming He was the Savior of black people and not white people, but that's a whole other issue (and, yes, there are nuts who believe that sort of thing out there).
Are you just as offended by all of the European art, throughout history, that depicted Jesus as a European? Most of the popular Jesus pictures with blonde hair that I see are probably about as racially accurate as a black Jesus. Of course we could solve the whole problem by not making graven images, but that's a whole other argument...
Then depicting Jesus as a woman to help a female better feel that Jesus is his Savior, too, thats OK too? I don't understand that reasoning. His words alone are reason enough to understand him. If his race or gender or even his religion has to be changed to get someone to believe, then that person isn't listening to the wordand incapable of understanding due to blindness through his own bigotry. This is PC gone amuck!
