Anger

Anger, in my opinion, is an emotion which holds the most ugliest facial expression. Also, showing such feelings is one of the most effective ways to destroy one's day the most. There are no cases where expressing anger has resulted in peaceful resolution. Truly, it is the last emotion you ever want to show. I believe that the following sources are most effective in provoking audience's anger:

Movie: Taken
Photo: Vulture Stalking a Child
Video: Crazy Girl Thanks God for Sending Tsunami to Japan
Celebrity: Floyd Mayweather Jr.
Movie: Hotel Rwanda
Event: 6/25 Incident
Song: Friday
Event: Bombing of S.Korea from N.Korea

The above list, in my opinion, lets audience to fully indulge their heart with anger and hatred. For example, the movie Taken enrages viewers by showing an innocent girl getting kidnapped and get involved with human trafficing. Other source, Hotel Rwanda provokes the audience's anger by showing a massive genocide of a group because of small differences from one another.

While reading the descriptions and reflections about the sources, I wish that you can also experience the same anger which I shall express.
