My argument has been consistent - the reality is that in the EU, USA and now in the UK, the actual terrorist acts that have taken place have been carried out by non-Muslims by a vast majority. That's what the stats show (Europol and FBI, and now UK police stats).
In the UK the overall threat from being caught up in terrorism is low for an individual, actually, it is 'very low' - as the HO quote above says.
But, to put it in perspective, we do have 99 actual terror attacks in one part of the UK which we can use as a benchmark. These were carried out by non-Muslims and prove my original point that the terror attacks by Muslims are not only a small minority of terror attacks, but vastly exaggerated by 'phobes.
I'm not asking anyone to believe in any fancy theory or jump through logic hoops. I'm just pointing out the cold, hard numbers of terrorist acts based on official figures.
Cheers,
