I think a lot about my wife who is a first gen American. Her parents worked hard to get out of Mexico and to where they are now. She sounds no different from myself and as American as apple pie (she makes some of the best) but is visibly Latina and also accepts being called "Mexican" and also sometimes refers to herself as such despite having never been to MX in her life. I'm also aware that this applies to a lot of other new Americans of color as well.
I wonder if this is also true for white new gen Americans? No wrong answers, and cheers.
