I think some people like myself see the current issue as an iceberg like problem. Systemic racism is composed of many tiny parts. This is not an either/or question, but a yes/and one. You can both not want to be killed and care about the casual and lazy use of language. We can as technologists, change this without stopping work on police reform for example. The defensiveness/resistance to change is much more interesting to me.

As for signalling, Sure we don't need to advertise it to ourselves and give accolades for something so simple. But we can do the bit and move on. I guess a lot of people are in love with the idea that if doing something is good then it must be being done in order to be _seen_ as doing good. That is bullshit unless you happen to know intent.
