I would encourage everyone to react more slowly and deliberately to stories like this that outrage them. This applies to companies firing people as well as people using the complex facts to support their existing points of view.
Slow down, everyone. Injustice will still be there for you after your blood pressure goes down.
That's why you should follow Prussian military complaint rules. The Prussian military allowed all soldiers to file complaints, even against officers. However the rule was that you could only file a complaint after one night had passed.
The idea is of course that you can think about what happened and reevalute it. Naturally the rule has its limits. If you are actively harassed then try to find help immediately. But in most cases it is a pretty good rule.
Now, if nothing else, I can look back and be proud that I wasn't baited into saying anything hostile or embarrassing.
In a way, since so many people acted so badly, it should be easier for everyone to apologize and de-escalate while saving face.
If either one of those three didn't happen, I think this could've been avoided.
Unfortunately, those who most need to heed this advice are the least likely to do so.
