On the day that Cuomo freaked out over being called Fredo, I archived the wiki page for "Fredo Corleone" and they now added Fredo as an "ethnic slur" https://archive.is/anPMW  That's the archive on the day that happened.  No mention of it being an ethnic slur, or even as an insult of any kind. Now the page https://en.wikipedia.org/wiki/Fredo_Corleone says at the bottom: In reference to Fredo Corleone being the weaker and less intelligent of his brothers, the term "Fredo" has become to refer to a weak member of a group, especially one of a number of siblings in a family, regardless of ethnicity.[2][3][4] In The Sopranos episode "Sentimental Education", when A.J.'s guidance counselor tells his English teacher to raise the grade of his term paper that was "90 percent CliffsNotes", the English teacher refers to A.J. as "Fredo Corleone", alluding to the fact that he is part of a powerful family despite being an unintelligent member. The official website of the Donald Trump 2020 presidential campaign offered "Fredo Unhinged" T-shirts following a viral YouTube video of CNN television journalist Chris Cuomo taking offence to being called "Fredo" by an apparent stranger, claiming it to be an ethnic slur.[5] Cuomo's comparison of the usage of "Fredo" to an ethnic slur caused debate on Twitter.[6] Edward Falco, the author of 2012 novel The Family Corleone said he agreed with Cuomo that “Fredo” was directed as an ethnic slur, not just meaning someone weak and incompetent but a weak and incompetent Italian. It sounds close to “Guido,” he said, a more prominent insult toward Italian Americans, though he said Cuomo went “overboard” when he had compared it to the n-word.[7] Others did not agree with his purported claim of it being an ethnic slur.[8]
