The problem with “onesideism” is that it fits the facts around a narrative. Onesidedness is a product of ideology, of a belief that something is true because it ought to be true. This is not merely the stuff of 5-year plans in Soviet Russia—this is the essence of Trumpism, embodied in his false claims of victory in the 2020 election.
I would only quibble that facts is a poor word selection, and perhaps assertions would be more accurate. Barber not only employs this in the context of Trumpism, but also The New York Times’ decision to remove opinion editor James Bennet.
