Answer:
This concept demonstrates an imagined community.
Step-by-step explanation:
This term was introduced by Benedict Anderson in 1983 to explain nationalism. An imagined community is imagined because an individual will never meet, know of or see every single individual within the community but he/she still identifies with it and in everyone's minds there will always be a sense of community and unison.
In this case, all the individuals from different backgrounds and obvious differences still see themselves as members of the larger community of "America", even though they will most likely never meet each other. This is an imagined community.
