Few tight-knit communities would consider those to be "values" (i.e. beliefs that are core to identity). Your view is also a bit of "throwing the baby out with the bath water." Humanity has lots of vices, and those vices are often amplified in tight-knit communities. But those shortcomings can be improved without undermining the social order or adopting pernicious individualism.

Again, I can't help but notice the irony of your assertion. What is the virtue in not being xenophobic against Bangladeshis, if you're going to condemn the way they structure their communities and raise their children?
