An even bigger issue is that if people think social justice is about niceness, it means they have fundamentally misunderstood privilege. Privilege does not mean you live in a world where people are nice to you and never insult you. It means you live in a world in which you, and people like you, are given systematic advantages over other people. Being marginalised does not mean people are always nasty to you, it means you live in a world in which many aspects of the cultural, social and economic systems are stacked against people like you. Some very privileged people have had awful experiences in life, but it does not erase their privilege.
