It's the American way. ;-)
Please read the rules a bit. Congress has changed the rules a few times.
We are in perfect agreement that birth on United States Soil (Or territory) is NOT required for Citizenship at Birth.
The best way to get the United States Government’s opinion of valid Citizenship is to go to the State Department website and look at an application for a Passport. Click on the information concerning claims of birthright citizenship for those born on foreign soil
That's because you can't cross an apple with a non-apple. It won't bear fruit. That rule doesn't apply with citizenship though. When you try it, you end up with something like this.
The Zonkey; American Citizenship as defined by idiots.
