My stance, is that you guys are over-reacting. They are telling GOOD BEHAVIOR. Social justice is basically saying that if you say or do something that is slightly bad,you should get executed.
It's paving the road to an almost strictly liberal mindset, where the society is recognized as evil and therefore must change as a whole to adapt to the needs of the individual. It implies "Don't say hurtful things," while it implies "no one is allowed to say these things." I consider myself a moderate liberal, but believe that the individual (as a concept) needs to improve before the society can do anything productive to improve. I denounce any sort of tyrannical movement endorsed by the government as "Protect people's feelings because they have low self-esteem and can't stand up for themselves." Sure, we shouldn't endorse being outright starfishs, but there's a better way than controlling people.
