That list is nonsensical. It draws on the bizarre, faulty idea that a single superficial cosmetic trait creates monolithic "racial cultures," which ignores the extreme fragmentation of groups now lumped together, and the violent hatred they've historically held for one another. Up until only a few decades ago, every European nation hated just about every other, with some shifting of alliances and enemies throughout the centuries. Varying African tribal lines still hate and slaughter each other, and would certainly take offense to being lumped in with their longstanding enemies. The various Asian nations still fear and hate each other, even if it's been toned down over the past few decades. Arabs and North Africans, though unified by a religion, are fragmented into sects within that, most of which decry all the others as heresy (the Sunni are basically the original sect; the Shia hold that a certain hereditary line related to Muhammad were rightfully the spiritual leaders, and basically treat them like Catholics treat saints, with shrines to them and whatnot; the heretical Wahhabi sect (of Sunni origin) sanctions the line of Saudi kings as rightful rulers, and takes various radical stances, in addition to backing violent proselytization, etc). Native Americans of all stripes carried out brutal genocide against one another, and most were all too eager to hop in bed with the European explorers to gain a leg up over their longstanding enemies or rivals.
Modern western culture only bears the slightest resemblance to the origins of any of its individual elements. To suggest that it is "white," because the vast majority of pieces ultimately originated with Europeans or their descendants, is silly. Really, if you want to argue that, then almost anything African Americans do is also "white," because most of them have some degree of European blood or another in them, and if something is "black" because it was created by Africans, then everything humans have ever done is "black," seeing as how we ultimately originated in Africa and all. Modern culture is what it is, and trying to alter it because of who created its predecessor is sort of fucked up.
