Which is based on what again....?
Fred.
Idealized traits that arent necessarily based in western standards of beauty. Do you even watch anime? The shyt is hyper everything. They draw big eyes because (in addition to being just easy to draw) they help in conveying story and intention as well as help differentiate people.
And again...this is how they draw themselves. Every society on earth has self depictions that may or may not have traits that are idealized that aren't indicative of the norm.
Are you really arguing why its OK to make a japanese person white? Even if they are fictional?
