I think the author is stretching his premise pretty much constantly throughout the entire article.

"To Lin, we (brown people) are lesser beings — not inherently so, of course — but because the burden of our struggle has exhausted its brave and noble warriors so fully, it prevents them from considering existential issues and experiencing the real, larger life that white people are living. "

No. To Lin, people living in poverty focus on parts of life Lin isn't interested in. It just so happens that in this world, white people happen to be less affected by poverty. White people in poverty and in war are in exactly the same boat and Lin doesn't suggest otherwise.

"Sadly, Lin has failed to see that he is an Asian-American man and somehow – somehow – his mind has managed to ponder “big ideas.” If Lin is an Asian-American man and Lin manages to ask, “How do I know if the universe is meaningless?” his own existence disproves his theory. And his theory proves the existence of The Default."

Lin's theory has nothing to do with this. Lin's theory is that people associate race with certain issues and Lin doesn't want to muddle up the themes of his writing by having readers trying to continue applying those associations. He doesn't make his character the "default" of white in order to do this, he simply doesn't apply any race to his characters. The author of this article seems to think Lin's characters are white for some reason.

'Or when analysts say things like, “Without blacks and Hispanics, the majority of Americans voted for Romney.” The assumption is that white voters, white politicians, white pundits are more real and are the only ones who can present objective solutions and analyses, since they are not burdened by self-interest.'

So there are only blacks, Hispanics, and whites? If you exclude blacks and Hispanics you also somehow automatically exclude Asians and native Americans?

"He wants to be accepted into black culture (unfortunately, only shown in “Spring Breakers” as drug culture)."

No, he wants to be accepted into street culture. He DOES want to be accepted into drug culture. It's not 'black culture' when people of every race who grow up in those environments end up behaving that way or because poverty affects people of color more significantly in this country, it just seems like another example of the author of the article's focus on race biasing his experience of the world.

The article seems to be more about the author than about people in general, but maybe I'm just out of touch.
