Or perhaps because of it.
When previous problematic tweets had emerged from other New York Times people, the paper of record had given them a pass. (But that was because they merely offended the military and Jews. When Quinn Norton, who is LGBT, had used problematic language, she was accused of homophobic and purged.)
Sarah Jeong's racist tweets about white people dovetail neatly with the Times' own attitude.
This is the same paper that ran pieces titled, "With a Loud Ovation, Baseball Shows Its Whiteness", "The Unbearable Whiteness of Baseball", "Watching While White: How Movies Tackled Race and Class in 2016", "Opinion | Should I Give Up on White People?", "Dear White America", "At New York Private Schools, Challenging White Privilege", "Looking 'White' In the Face", and countless others.
That's a small sample of the same basic leftist intersectional discourse behind Sarah Jeong's racism.
At Scripps College in Claremont, California, all incoming students receive a “survival guide” designed to alert the newcomers to the racism lurking insidiously in the dark corners of white people’s hearts. One entry in this manual, titled “Dear White Students,” declares that “we as white students must identify the ways that we are engaging in the perpetuation of white supremacy and work to unlearn our racism”; that racism is often manifested in “subtle ways through language” and “the perpetuation of white supremacist values like perfectionism [and] individualism”; that “reverse racism does not exist because there are no institutions that were founded with the intention of discriminating against white people on the basis of their skin”; and that the “anger” of nonwhites “is a legitimate response to oppression, as is … a general distaste [for] or hatred of white people.
This is the same attitude that we see in the New York Times, its acceptance of Jeong's racism and its own attacks on "whiteness".
