They have noble goals, but the approach is wrong in a lot of cases. Many of the people have the same toxic personalities that they rail against so loudly.
There is no problem with an individuals choosing not to engage based on their own experience. The problem with cancel culture is that we are encouraged to treat people as "cancelled" based on hearsay.
You're under no obligation to do anything. Individuals are simply exercising their own right not to engage based on their own experience.
