if your white your caucasion, but if your south west european your 'hispanic', if your from west asia your 'arab' and if your from east asia your 'oriental'

i think oriental, hispanic and arab are more offensive that black or white

so the oposite caucasion is non-caucasion, as the oposite of white is black? i think thats the best way to do it, caucasion or no-cau.
