Yes I do know what you mean, and I'll say again , they know all this, they couldn't be more 'educated', the problem is there is a tolerance , both from the white liberals and Muslim society in the UK for vehement anti western views, why else would Muslims of Pakistani and Bangladeshi origin be...
With all due respect, these girls, and others like them, live in a western country with huge amounts of media ,news outlets and social networking at their fingertips, there have been medical students who've left Britain to join ISIS, they couldn't be more 'educated'.
But it's not full of Muslims who live a strict Muslim lifestyle you dolt , that's what secular means and is the basis for my statement that the strict Muslim lifestyle is not compatible with living and integrating in the west, hopefully YOU can grasp that.
