Mosiah 24

 I find it interesting that - 

"...Amulon began to exercise authority over Alma and his brethren, and began to persecute him, and cause that his children should persecute their children."  (Mosiah 24:8)

Amulon taught his children to hate Alma's children.  We see this much in the world as different ethical and religious groups are taught to hate each other.
