There's a difference between being a social activist and being a SJW. A SJW will doxx people they don't like, spread bogus studies as facts, answer well thought out rebuttals with "FUCK OFF!!", and be complete hypocrites. If you don't do those or things like it, you're not a SJW, you're a social activist.
