To be fair to the NYT -- to be the devil's advocate, as it were:
The reason they backpedaled on the Tom Cotton piece wasn't because of the basic ideas expressed (the idea of sending federal troops, as such): but because the surrounding text was, well, basically unhinged and disconnected from reality -- and in that sense, basically irresponsible and (considering the historical moment) profoundly inflammatory.
As the Times explained in its notice explaining its decision to formally backpedal:
For example, the published piece presents as facts assertions about the role of “cadres of left-wing radicals like antifa”; in fact, those allegations have not been substantiated and have been widely questioned. Editors should have sought further corroboration of those assertions, or removed them from the piece. The assertion that police officers “bore the brunt” of the violence is an overstatement that should have been challenged.
That's why the editor who approved this hot, steaming piece of mindless -- and essentially pro-violence -- drivel got "cancelled".
