> SJW Ah the SJW boogyman. A quick way to get anybody with a functioning brain to dismiss everything you say.
It's just the counterpart of the "racist" boogyman. Why is it terrible to dismiss people by calling them SJWs, but not calling them racist.
1) SJW isn't a bad thing, like racism. social justice (the literal term) is what all people want in their society. It's preached by nearly every religion (the idea that the poor are equal to the rich, the black people equal to the white, etc).
2) Racist is an adjective but SJW is a group affiliation often attributed to people who don't wish to be affiliated that way. A person can say a racist thing, but no one can do an SJW thing. We can qualify certain things and statements as racist or not. We cannot do the same with SJW. SJW will always be used to denigrate someone. Racist, however, can be used analytically and without malice.
