Posting things that you’re offended by on Facebook doesn’t solve anything.
If you don’t like something, don’t give it an audience.
Most of the time, it’s a publicity stunt by the person/group that you’re offended by, anyway.
If you want something to die a death, deny its existence. There are plenty of things I deny the existence of.
Using Facebook as a launching pad for your fears and disgust with the world just feeds the frenzy.
