“Brandon wrote that Murray has “represented Muslims as a collective threat,” and described his time worked at CSC as a “constant struggle to “de-radicalise” Murray and to ensure that the centre’s output targeted only Islamists – and not Muslims as a whole.””
That's the problem though, isn't it? Murray is not radical on this issue; he is logical. When it is not possible to filter out extremists from the many illegal immigrants, and the existing muslim communities, then the only option is to see muslims as a collective threat. Even those muslims who have culturally assimilated (and there are many) are not doing anything (with very few exceptions), despite being in the best position to address what is happening. So, in effect, they are supporting islamic and cultural extremism through their silence, i.e. a collective threat.
