Ok, my ideas. Some major points: 
 # Historical versus modern. (aka, two major sections) 
 # Cultural relativism. (how to intepret other cultures: own morals verus their morals (and maybe have a clear cut case and discuss that)) 
 # Different layers. Many cultures have double standards and use different norms for what they condemm in the open and do in the dark. 
 Some substantial points: 
 # Equal rights 
 US section: 
 # Current debate 
 ##Army 
 ##etc.
