I disagree. Calling the team American is not propaganda. It's only a label, propaganda takes more assertive action than simply applying a label that more or less correctly describes what the team is about. Telling the American public that American Freedom is a better team than Justice Elite because JE supports bad UN initiatives like elite registration, and doing so in a formal manner, such as with commercials and billboards and posters and such, that's propaganda.
I kinda understand where you're coming from though. 'American' doesn't quite represent what the group is properly in your point of view, that I can understand. I still don't see a consensus on a name though. I might have to make a poll or something.
