When did they immigrate from Argentina?
It reminds me of the sense of alienation some of the terrorists who had come from various countries and moved to western nations like Germany, and APPEARED to assimilate well. But they didn't. They felt apart. Trapped between two worlds.
I understand that a bit. As a child of immigrants there were things that stood out about me when I was young. I spoke differently. Dressed
Differently. Other kids and even their parents seemed to view me as not that American.
But in Europe I was viewed by my extended family and friends as not really belonging. As their "foreign" and very American relation. (I remember an aunt telling me "Gosh you even walk like an American!").
It can be super isolating and if someone has a mental health issue and/or feelings of entitlement, that can erupt into violent rages or psychosis.
I think immigrants who have a large immigrant community in the new nation tend to do better (as do their kids) because they have help assimilating but also holding on to a bit of home and a support network of people who are going through the same thing.
Belonging and being accepted are so important to mental health.
