Arguments about cultural beliefs( A. Bugubayev)

I found out that people in the West believe that women and men have the same rights, and people in the East,i would say Middle East believe that women have less rights. We even discussed about that. But i still cannot understand, why people from Middle East( Afghanistan, Pakistan and etc.) are still believe in that, even if they moved to the West ( America)? Why they are still segregating each other in their own inner society, even if it is unlawful in America? I think, the new generation have to live with their new traditions and new ways of life, but still remembering their roots.
