ELI5: What is the difference between Sunnis, Shites, Baathists, Kurds, and Wahabist?

I'm trying to understand what their differences are and why they always seem to be culturally clashing and at odds with each other. Can anyone break it down? Also can anyone explain to me why they haven't tried re-drawing borders to make cultural sense and allow them to each have their own way of life in their own respective regional areas?

The Sunnis and Shia are two groups of Islam that split when there was a disagreement over who should have taken over as king (caliph) after the Prophet Mohammad died.  
After the split they developed slightly different rules and rituals, think Protestants and Catholics.  
Baathist were the people who supported Saddam Hussein's Ba'ath Party, think more along the lines of Republicans or Democrats.      
Kurds are an ethnic group. Most are Sunnis, but there are also Shia, Christian, Agnostic and Atheist Kurds. Think more along the lines of Caucasians or Hispanics.  
Wahabism is a movement within Sunni Islam. Think more along the lines of the Puritans. It seeks to change Sunni Islam to be much more conservative.     
So if you are a Sunni, you are not a Shia and vice versa.  
Baathists or Kurd you can be either or none, it doesn't matter what your religious beliefs are.  
If you are a Wahabist, you are a Sunni, but not all Sunnis are Wahabist.
