Social justice, as a concept, has existed for millennia — at least as long as society has had inequity and inequality and there were individuals enlightened enough to question this. When we study history, we see, as the American Transcendentalist Theodore Parker famously wrote, “the arc [of the moral universe]…bends towards justice.” And this seems relatively evident when one looks at history as a single plot line. Things improve. And, if history is read as a book, the supporters of social justice are typically deemed the heroes, the opponents of it the villains.
And perhaps it’s my liberal heart speaking, the fact that I grew up in a liberal town, learned US history from a capital-S Socialist, and/or went to one of the most liberal universities in the country, but I view this is a good thing. The idea that societal ills should be remedied such that one group is not given an unfair advantage over another is not, to me, a radical idea.
