Why do people come to America? Why did the Pilgrims and everyone else that followed come to America? To get away from other governments telling them how to live their lives. America doesnt do that and it shouldnt in this instance.
I dont know exactly what it means to be an American or to be patriotic or who is more patriotic than someone else. Patriotic is certainly not criticizing other Americans for playing for other countries in sports. Thats unAmerican. In other countries that would not be so easily tolerated or ignored as it is here. You can do what you want to do.
There are plenty of Latinos and Muslims in the military. Now if Giovanni Lanaro decided to go fight for Mexico in a future Mexican-American war, well, that obv would be un-American.
