I get your point but I do think that "European culture" (that sounds strange to my American ears as I typically think of the individual nations, not Europe as a whole) is more homogeneous than Asian culture. Not that it is homogeneous, just closer on the spectrum.
Isn't it strange though that we agglomerate all of Asia into one, when it has two constituent parts that are larger than all of Europe combined, and with another billion or two spread out among a bunch of other smaller countries (the 8th most populous of which being larger than the most populous country in Europe)?
Hell, if Germany was a province of China, it'd barely crack the top five in population. Spain wouldn't even crack the top 10. West Bengal in India would be the largest country in Europe, and it's only the fourth largest state. UP is twice its size.

Wow. This completely blew my mind. It's incredibly ignorant how we (Americans) lump the provinces, languages, cultures, and 55 ethnicities[0] of China into Chinese people, and then lump Chinese people into Asians.
