Bullocks! What cultural shock? Neither British nor Syrian culture is homogenous. There are almost 2.5 million British citizens who believe in the same value system that most Syrian refugees have. They are known as practicing Muslims, and although most of them come from a non-Arab background, there be enough citizens of Arab background, enough Syrian with dual nationality and enough cultural similarities between all practicing Muslims to make most Syrian refugees able to find communities where the cultural shock is manageable for all involved. There is also bound to be a certain social segment among the refugees that will find much comfort in the basic freedoms available to them in British society, and who will seek to maintain cordial human interaction with all around them irrespective of their confessional background. In all cases, and considering that the UK will be admitting a few thousands refugees at most, and that most of them will be busy for years to come trying to make a normal life for themselves in their new country, the possibility for any trouble-making is pretty minimal.
