Hmmmmm ... if the four guys with medals were the American team then two are "white", one looks east Asian, and the other looks south Asian (perhaps Indian?). I wonder how many of the other 99 nations' teams had that much diversity. IOW, the "significance" of what these DU-folk "saw" in that picture is what those DU-folk brought to it in their own hearts.
DU-folk seem unable to conceive of the fact that these young men - and not any women, blacks, Hispanics, and (apparently) Native Americans - are there because of their choices, un-coerced or -forced by government fiat.
I hope those Math Olympiad winners were able to spend some time there in Chiang Mai. I've heard it's a beautiful and interesting city.
