As Christians the Chaldeans and Copts do not share the Moslem intent to convert, enslave, or kill the rest of humanity. As Christians they are not intent on skewing our own culture. As fervent believers, as most of them are, they will not sag onto the welfare rolls or change the ehnicity of the prison population, at least not the first generation or two, not until they become Americanized.
Interesting point. This is an issue not just for Middle Eastern or Viet Christians, but for any Christian immigrants. The Hmong communities, both Catholic and Protestant, are having problems with "assimilation" (the bad kind!) of their young people after a generation or two in the United States.
