It's questionable in what way wokeness exists at all without a clear definition. Graham's definition is more personal judgment than definition, but according to him, whatever he thinks it is seems to be about 30 years old. Bolshevik-Mensheviks and Trotskyists-Stalinists sects appeared faster than that (the Bolsheviks and Mensheviks split a mere 5 years after the creation of the party).
Also, I think Sam Kriss's point about sects and splits was meant to be taken in humour. Funnily enough, both Kriss and Graham seem obsessed with convincing the reader they're not boring. But whereas Graham's writing is predictable though he repeatedly insists on telling the reader that his old-school conventionalism is the true rebelliousness, Kriss writes provocatively in a way that's supposed to make you unsure of whether he's serious or not. In any event, Kriss's writing is at least always entertaining even when it isn't interesting.
