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.
Try replacing "sexual harassment" with "murder" or "robbery" and see if it still makes sense.
A lot of problems can only addressed systemically.
Murder? Yes, an excellent start to solving this problem is to not murder anybody. That's really the single most important thing you do.
And yet, history shows, other people are going to do murders and simply not murdering people yourself is not sufficient to deal with this problem. You need to intervene or call for help if you see somebody getting murdered, and we need some sort of system to deal with murderers and protect other people from them, etc.
If murder is too extreme a metaphor for the anti-woke crowd, how about pissing on the bathroom floor? It's great if you are not pissing on the floor, but somebody is and we all have to walk on that floor, so we need to have some kind of community standards around it, and also somebody needs to clean up that piss.
