To be fair, he does say the above, which is close enough. The problem with asking "what if they're right" is that there's no single formulation of beliefs shared universally by such large and diverse group, so you can't consider whether they are right or not, only whether each individual expression is.

The whole idea of woke (in the non pejorative sense) is that you’ve done the work to perceive the actual problem.
That statement shows that he hasn’t, which I think undermines the good parts of the essay.
From what you say, anyone who disagrees about the nature or severity of the problem hasn't done the work and is flat out wrong.
If so, then the whole idea of wokeness collapses into the state of infallible enlightenment where everything one says is correct.
And the polarized ends of woke and anti-woke shouting aren’t going to achieve that.
So it’s important to engage with the (non-shouty) people in our lives who we can have those discussions with.
