Like it or not, the fact is there is an extraordinary level of violence occuring within Muslim majority countries and also whereever Muslims have settled in Western countries (France, UK etc.). This violence takes many forms, from acts of terrorism to brutal acid attacks to sex traficking. Until there is a better awareness as to what to do about this and effective strategies developed to counter this violence, it is very prudent to reduce the risk and exposure to this violence in the short to medium term. 

The world is a big place and labour market needs can be met with people from non-Muslim countries until the violence goes down.
