I don’t need to, it’s not an Islam/Muslim fixated argument I have ever made.
I think it’s bigoted to habitually juxtaposition discussion of immigration with your Islam/Muslim fixation, doubly so when you continually frame your views of a whole religion and its adherents within the crimes committed by individuals, not by the whole Muslim community.
Given it’s been my experience that individual adherents to any religion vary widely in how ‘adherent’ they are, I’m at a bit of a loss to understand on what basis you claim to know there are ‘thousands of young male Islamists’ being imported to the UK.
Perhaps you have a basis for this statement, if so do you care to share?
