The throng of alumni have complained sociology professor Nathan Cartagena has repeatedly exhibited "left-wing racial politics wrapped in a patina of 'Christianese,'" according to The Christian Post.
Laurie Higgins of Breakthrough Ideas notes he's not the only one.

“It is not just Cartagena, although he's perhaps the worst, but there are others who are close to it. He assigned students a paper to write about the glories of socialism recently, within the last calendar year … the glories of socialism."
An analysis of Cartagena’s work asserts that he has claimed God called him "to love and serve the Church as a race scholar," and that he attempts to mix traditional Christian scholarship with Critical Race Theory. It quoted one of the

professor's writings saying there is a historic link between "Christ's broken body" and the "redemptive conceptions of whiteness and white nationalism."
Cartagena also endorsed a comparison of President Donald Trump to Pharaoh in the book of Exodus, accused Christians of "sinful blather" in their opposition to Marxism, and maintained that "we are in (antiracist author Ibram X.) Kendi's debt."
Higgins says the alumni are not only calling for Cartagena's removal but school president Philip Ryken's resignation as well.
“The only conclusions I can come to is either that, that Ryken internally leans left, or that he's just a weak ineffectual leader. He has allowed this malignancy to grow at Wheaton, and that is he's terrified of bad PR."
