Personally I don't like the term "social justice" for the same reason I don't like people like Sarkeesian and Quinn. They take a legitmate issue and agendize it to the point that the goal of a movement and/or meaning of a term mutates into something it was never intended to be. I like the idea of equal justice and treatment for everyone in society. But the term "social justice" has been used and abused by the "Social Justice Warriors" to the point that it has become a negative term for many. That's why it really fits in my mind. They don't stand for actual social justice. They satnd for their own warped vision of what they think justice should be.
The "If your not a feminist you're a misogynist" quote comes to mind.
“The greatness of a nation and its moral progress can be judged by the way its animals are treated.” - Mahatma Gandhi
