They are people with a certain ideological outlook, not an immutable hive-mind block. I'd imagine there are plenty of liberals who would feel, if not outraged, very uncomfortable seeing footage of aboriginals being held down and forcibly jabbed by the military. If they just turn away, then there's knowledge that that's what they did. Events like these can sway people to change their position. Just a there are many on this forum who were once liberals and their minds were changed by events in their lives.Liberals have already abandoned their supposed principals. Big corporations are now good. Big pharma is now good. Western medicine is now good. Police brutality and security state is now good. Banking and big finance is now good. Critical thinking is now bad. Rage Against the Machine is now the machine.
Why would this change anything?
