I can understand why you'd want to generalize it...doing so let's you claim that those who have less desirable views of social justice don't truly represent it. Redefining words to fit your personal beliefs doesn't change reality though.
I'm not redefining words.
I happen to be part of a pretty active network of people involved in social justice in all sorts of spheres. Here's a random sample of things hitting my inbox in the last week under the general heading of social justice:
- promotion of a march in support of refugees
- promotion of a women's leadership breakfast
- promotion of a workshop on how religious narratives "may unfold into human stories that can build communities of love and justice"
- correspondence about a Bible study series on "Isaiah's Cry for Justice"
- this article:
Lighting the Way: How Pollinate Energy Is Making Money and Doing Good - Social Change Central
- information about a voucher scheme in support of social enterprises, and other grants for those with ideas to make a positive difference in their community
- information about a sustainable investing challenge
- awards for those involved in working towards gender equality and environmental protection
- information about a fellowship in leadership for young people
- a request for stories about ethical/sustainable travel
All of this sits under the broad heading of social justice, and not because I put it there. Those who want to claim social justice is just about race relations or whatever are, as I see it, artificially narrowing a vibrant and diverse field of activism and interest.
