Eritrea and Somaila...the US has let in thousands of them. I am more familiar with the Somali and Sudanese Mohameddans. The Eritreans I know are Christian and having a rough time back in their country.
Watch out is all I can say. Put it this way - I find it easier to deal with Yemenis "off the boat" than with Somalis who have been here for years.
For those of you who know any Somalis do not let the smiles fool you. They have vicious temperaments when aroused (especially the males).
What is really hilarious about this is it seems there are no real muslim virgins to be found - everything I read seems to indicate they are deflowered by their brothers, fathers, etc., then passed around to the neighbors to settle grievances and debts....before being burned publically...Allah is another word for Satan....
