Social justice warrior

Social justice warrior (also known as SJW), is a pejorative term for people who support feminism or have left-wing opinions. Originally the term social justice warrior was used by people who generally supported left-wing politics and who were activists for social justice and meant it as a good thing. 
In relation to the video games industry.
After the Gamergate controversy where Carl Benjamin and Milo Yiannopoulos accused people who didn’t think video game journalism was being used by feminists to spread political correctness of being social justice warriors, the name became a pejorative for someone who wanted video games and popular culture to be more politically correct or someone who was easily offended.
