If you collect 100 red ants and 100 black ants and put them in a glass jar, nothing happens, but if you take the jar, shake it hard and leave it on the table, the ants will start killing each other.
Blacks think that reds are enemies, while reds think that blacks are enemies, when the real enemy is the person who shook the pitcher.
The same thing happens in society:
-Opposition against coalition
-Poor versus rich
-Left versus right
-Young vs old
-Women versus men
-etc.
Before we start fighting each other, we must ask ourselves: -Who shook the pitcher?
