Home of The Brave
Being an Advocate
Treating people unfairly is unacceptable, especially because of looks, or even race. Preventing these terrible things i would do....
1. Pass laws through (If they haven't already)
2. If the problem is involved with guns, shut down gun shops, or knife, or other weapon shops. Or even have permits required, or possible to background checks on people who attempt to get a permit.
3. Have Africa's president make speeches that are convincing to people not to hurt people. (This would probably the hardest solution)
Being honest here, this is a very challenging social issue to find a solution for.
