It's okay, so long as he prefaces the term with the word "Inscrutable".
Example: Inscrutable Orientals.
Never can understand why orientals want to be called “Asians”. Asia is so large, all the way from Turkey in the western end on down to Japan in the east, and includes the Indian sub-continent. Asia has all 3 racial and ethnic groups in abundance. Therefore the term Asian does not describe any ethnic/racial group.
On the other hand, Orientals should be proud of their ancient history and economies which are growing much faster than anyone in the Western world.
During my fifty years in the Land of the Rising Sun I learned to pronounce it ‘Ollienters.’
