I don't believe that PM May's response is either dishonest or impractical. She noted, in particular, that too great a proportion of British Muslims reject the value of pluralism and also said that Britons must engage in a frank and uncomfortable discussion about the consequences of this. She didn't comment on the roots of extremism outside of her own country. And, notably, she pivoted away from the patent excuses for extremism, which characterize it as a somehow understandable reactionary impulse generated by conditions imposed by the dominant (Western) population. The reality is that extremism is also being fueled and buttressed by attitudes, values and behaviors within the Muslim population, even if only among a minority. To me, it seems a startlingly honest assessment (for an modern politician, at least) to assert that all aspects of this problem must be examined, even if some don't want to contemplate the implications of this.
