The fear that hubby might have a wife and kids somewhere is definitely NOT limited to MENA or Islam - in Hinduism bigamy is very rarely tolerated though in Nepal at least it is against the law...that said it is hard to enforce because it is socially acceptable to just have a temple marriage with no papers - so yes I have had the fear that maybe he has a village wife stowed away waiting for him to get his GC, though more and more I am trusting him and in my heart I don't feel that he would do that. His family couldn't afford it, for one thing...
There is also some discussion of this on the Sub-Saharan forum. So it is definitely not a bigoted reaction against MENA men. There have even been cases of bigamy with American men who have somehow managed to have wives in different states.... 
But how many women married to American men are worried about their husbands having a second wife or consider it something that goes along with being married to an American man even though it happens here?
Statistics in Egypt for polygyny are often equal to estimates for the adult male gay population in the United States, but how many of us worried that our previous husbands/boyfriends were gay? I doubt many, but it is statistically more probable. Terrorism is even a greater stretch.
I think it is obvious that many of the issues addressed in this thread are based in negative stereotypes rather than any reality-based probability. Just because one can be applied to Hindus or Subsaharans as well doesn't make it less rooted in generalizations. How many of us approached relationships with American men and worried that they were pedophiles or other unlikely extremes?
Telling her how great she is or that it is "normal" to wonder if your husband is a terrorist isn't going to tell her through these issues. If thinking about why some might hold these issues and if they are based in prejudice is too out of bounds for this forum or if we want to dismiss that we can have prejudices simply because we have married MENA men (this reminds me of that old ad with little Timmy learning about prejudice), than completely disregard why she and others may have these views and look at it from a statistical perspective alone. The numbers alone should be persuasive to realize these are not things are likely to happen and the issues can only negatively serve their marriage. Lingering doubts and a lack of trust never benefit a marriage, no matter how we try not to the let our spouse know we have them.
Do other women in this forum really share the concern that there husband is a terrorist or has a secret second wife and children?
Personally,.... no.
