Social justice warrior. SJW, to use the not-quite-clever abbreviation. Why would that ever be an insult with any real bite? To those who use that term in a derogatory way, I suspect it sounds funny because they’ve never lived a life where societal injustice has ever left a mark on them or anyone they particularly care about. Do you occupy a world of privilege without ever actually looking outward with empathy or compassion? Then I suppose the idea of people who fight for the dignity and equity of vulnerable populations might seem silly to you. I’ll give you that.
