Animal or child abuse.
Terrorist attacks .

My health
Child molesters!
Any kind of threat to the President. I don't care how much someone doesn't like a President . . . That is nothing to joke about.
National Security does not play games where this is concerned.
Also, I would have to side with Yin about Child molester or abusers. This should never be taken lightly . . . And should spark disgust or outrage.
Terrorist torturing/killing people publically. I feel that we have become desensitized when it comes to this . . . Each time should fuel the fire in our bellies to eradicate any organization that kills, maims or tortures people for not sharing a belief.
Personally ... Nothing.
