"Kahn" is a pretty common Indian surname. While, there might be few Hitlers left in the wold, I don't think everybdy named Kahn (or Green, for that matter) would change their names in reaction to the actions of one man.
I liked "Gods and Men" despite its flaws, and will reserve judgement on "Reegades", as we all should, until I see the finished project.
"Khan," not "Kahn."
Nothing personal, just a pet peeve. I've even seen professional magazines spell it wrong!
