I'm not sure that's true. Wokeness doesn't focus on actual harassment; it focuses on accusations of harassment, with a definition of "harassment" that is highly subjective and doesn't necessarily correlate very well with actual harassment.
> how we can do things like take sexual harassment more seriously
The problem is not that we need to take, for example, sexual harassment "more seriously". The problem is how to reduce how often actual sexual harassment happens. "Taking it more seriously" is a very vague and ineffective way to do that.
While I agree that this is true, I think the point pg makes in his article could be extended to a general rule that, if you find your earnest desire to do good things is leading you to embrace something like wokeness, you need to take a step back. The best way to do good things is to do good things--in other words, to find specific things that you can do that are good, based on your specific knowledge of particular people and particular cases, and do them. Participating in general efforts to micromanage people to make them do good things, or to stop them from doing bad things, which is what wokeness is, is a very poor way to make use of your earnest desire to good things.
