Sherman Alexie explains why he didn't oust a poem from The Best American Poetry 2015 after he found the author, a white man, had used a Chinese pseudonym.

As the guest editor of the annual volume, Alexie (a Native American) had some rules for himself in choosing the poems, including:

Rule #5: I will pay close attention to the poets and poems that have been underrepresented in the past. So that means I will carefully look for great poems by women and people of color....

Most of the rules — please read the whole thing — were about neutrality and not showing favoritism.  60% of the poems he chose were written by women, 40% by "people of color." One poem Alexie chose turned out to have been written by a white male, Michael Derrick Hudson, who'd adopted the pseudonym Yi-Fen Chou — in Alexie's words — "as a means of subverting what he believes to be a politically correct poetry business." Alexie only learned of the ruse after he picked the poem, and he was "angry at the subterfuge," but he decided to keep the poem in the anthology and to share his soul-searching over what to do about "this colonial theft."
