Well,I for one am happy about the last statistic.
The odd thing about where I live in Seattle is the large number of Somalians and Ethiopians I have encountered here.
Then there are the Bengalis, another bunch of Moose Limbs open to radical influence and who refuse to assimilate. Just drop by the corner of Church avenues and MacDonald avenues in Brooklyn and see them all dressed in the traditional finery as if they were back in Dacca. Their kids dress like they were back in Bengal instead of wearing American dress.
I think in a couple of generations we should not be surprised that like Orthodox jews who have been here a few generations they will still neither look like us nor adapt to our ways but will remain a separate "colony" (community?).
Enough with the multiculturalist crap already!!!!
