did you guys notice the part with: "we don't speak....Lebanese, or ARABIC"
this reminds me of an incident when i was helping a friend fill up some australian immigration self-assessment test. we got to a part where one should list all languages spoken and on the drop-down list it said "Arabic, including Lebanese".
this is so funny. why do aussies think Lebanese speak an alien form of arabic? :D

As for the topic of discussion (finally) I tend to agree with what e46M3 said. Immigrants for some reason almost never adapt to the societies they're living in. I guess they just address the topic of culture & heritage as if it were a matter of life and death. Instead of forming a melting pot of countless cultures you'd find that most immigrants opt for gathering up around each other and living in their own "bubble" -if i may say-, while refusing to let any "outsiders" into their lives. That being said I also think it's only a part of human nature for seek and befriend those of similar backgrounds, but it certainly does not help alleviate the situation in the least.
