Muting people and moving on is exactly what happened in another form during a certain World War, people overlooked the changes and what was going on and turned a blind eye to it because they didn't want to try changing it at the time. Laziness and inability to think we can change something is the kind of passive thinking the world doesn't need, and if you think one or two people just muting someone so they don't see what they post, but still acknowledging that they will be running around and continuing with their behavior, is not what a decent person should be doing.
