When dealing with that kind of scum, just lie without prejudice or the slightest bit of conscience and pick up your checks. Check whatever boxes help you. Screw ‘em. Someday I’ll relate the story of a young white fellow I know who shockingly got accepted at a very prestigious university simply because he checked the ‘African-American’ box on his application. Nobody goes back and double checks anything. He just had to put up with lots of junk mail from various black student support groups and fraternities for awhile.
Probably an Urban Legend (maybe I read it on this board) but there was a story about a white student who checked the "Native American" box. When asked what tribe, he said, "SoSueMe".
