You clearly and obviously have no clue as to the origins of the dual nationality laws and their reasoning(s) as to why they were put in to effect.
I am sure you're Shawnee or Deleware, though, right? Proper North American?
I assume not. You're probably one of those Turdbiscuits that were yelling "CAREER IS OVER" to JB.
Furthermore, it is easy to see, search, and find that myself (along with many others such as Scourge) also root and advocate for our US representatives first - then the gents with US ties.
Were Lee and RBY to meet in Paris, I am rooting for Lee 10/10 times, regardless of how much of an ignoramus you care to be. I will then root for RBY over everyone else (aside for maybe Cruz, who I will root for both equally).
The same for 86 KG. I am rooting for Brooks over everyone, including Amine - despite both of us being alumni of the University of Michigan. I might then root for Amine over Ramos, though - sue me.
Hell, after Dhesi and Smith at 125 KG, I will probably root for Abdelmottaleb over the other gents simply because Hemida has been attempting to wrestle for them for the last ~decade.
Quit being a bitter xenophobe. This is a suggestion, not a requirement.
