Social Justice Warriors

I have been recently made aware that there is such a thing as a "Social Justice Warrior."  From many sources, I now realize that the term morphed into a pejorative a few years ago.  So, what do I, an open-minded male, conclude from this?  I choose to accept the RationalWiki take on this term.  If you disagree with my opinion, please concisely, succinctly and respectfully show me the error of my ways.
