SJW is not a term used for people who try to make the world a better place, and it's not a term used to describe people who advocate for social justice either. It's a derogatory term used to describe people who advocate for things just to make themselves look better, while often not caring about whether what they're advocating for is actually true or not, as can be seen by their reactions - an SJW will continue to complain about the unadjusted wage gap ("77c per dollar for the same work!") even after being shown that it's nonsense because he needs big problems to rally against, a sincere advocate for social justice will not, and either rally against the very real adjusted wage gap of a few percentage points, or move on to a more important issue. SJWs care about looking good and feeling morally righteous, they do not care about solving problems. Which is why I do believe pointing at SJWs and showing how they're hypocrites does make the world a better place. As long as the discourse is dominated by people who have unsound reasons for their advocacy, progress will be difficult.
