Think of it as a ghetto if you want to, Chance, but you of all people will know that I do not live in a comfort zone. I like adventure and pushing out the boundaries.
I was answering the specific question about why so many, not all, choose to live amongst high concentrations of their compatriots and made the comparison with areas that others, not myself, call ghettos.
The only place that I feel relaxed and at home around where I live is in an immigrant ghetto, Amiens Nord, I went there Sunday morning and its been at least 6 months since I was last able to, but I am not an Arab or Muslim, I feel at home because there, all of us of many varied nationalities are immigrants, I am not treated as an outsider.
I wasn't in the Dordogne either, I can see the attraction.
