I hear this all the time, but it seems so disingenuous. There are so many national examples that no reasonable person could consider to be any of the above:
* A hispanic man was fired for accidentally making the "ok" symbol
* A data scientist was canned for citing a prominent black academic's research about the efficacy of nonviolent protest
* A journalist was forced to issue an apology for interviewing a black man who was happy about BLM but wished there was more attention on issues of violence in his community
Frothing racists indeed.
In light of cases like this, I don't know how anyone can think that cancel culture is just "punching up" or "criticizing people" or "going for people who want to use hate speech".
