What makes immigrants "good Americans" isn't necessarily abandoning their culture and adopting ours. Vietnamese refugees are a good example. I worked with many Vietnamese over the years and I have a profound respect for them. They adopted the "American way" while still holding onto their culture. The people I worked with came here as refugees when they were young, went to college, got degrees and worked the same job as me. They really fit in here because their cultures were compatible in that they had a sense of personal responsibility, and accountability. They seemed to fully understand the concepts of freedom, democracy and self-determination and I think they thrived in a new land because of that. They found a way to adapt to American culture without replacing their own.
This is acceptable. At least in my eyes.
We are surrounded by Hispanics in my area. For the most part they are assimilating as they keep up their homes, the kids are as well mannered as anyone elses and more so in some respects. They maintain their music/food and the ability to throw a good party. They do not drive worth a hoot but heck.....who does these days. English is at least tolerable.
Thing is, they are mostly Catholic so all of this as in being family oriented is taught in this religion.
Having little experience with Muslims beyond benny the bomber on the news it is tough to get a handle on the culture.
I have dealt with the culture in the business world when running a service truck in the HVAC trade. They are ruthless and will go whack on you in a heart beat.
When we sold off our rentals we dealt with a few family's and I did not have a good experience with any of them. One I really wanted to knock his teeth out as he treated my wife and daughter very badly as is their way as I understand it. He was removed from my area.
I am still fearful of how this will work out.
