On the "Jesus was white side", the icon and shroud arguments are both irrelevant.
Doesn't matter how old the icon is, it's not gonna be an actual portrait of him made by someone who actually met him. And if you think you can somehow prove that the author actually met Jesus in person... good luck with that.
As for the shroud, it's supposed origin was never proven. And the only carbon dating the Catholic Church allowed on it placed it centuries after Christ.
The rest seem like good arguments. If I cared about the debate I'd look further into them.

As for the "Jesus was black" side, if anyone actually thinks Jesus was African, they're 100% moron. The Middle-East is not in Africa. At best you can hope for Jesus to be an average Middle Easterner, which will be more "brown" than the average modern Caucasian, but fundamentally won't look different enough that you can't mistake him for a tanned Caucasian (and something tells me 2000 years ago people got more sun exposure than today).

TL;DR: Jesus definitely wasn't African/black. He was probably an average Middle-Easterner, but people overestimate the differences between a "brown" Middle-East person, and a Caucasian.
