I think you may be wasting your time. They are pre programmed not to use the word against anyone on ideological… oh and as someone said political grounds.
I don't know who you are arguing with here, you're certainly not engaging anyone on this thread in good faith.
All of us accept that Islamic terrorism is a thing, and has been an underlying ideology in a number prominent brutal murders and attacks in the UK and the world. I'm (we're) happy to attribute that when it's the cause, and helps us understand why and how something happened.
What we are saying is from the information we have available in the public domain in this particular case he wasn't a Muslim, wasn't engaged with Islamism, didn't have any sympathies with Islamic beliefs or values, and didn't commit these crimes to further Islamic causes. (Nor, for what it's worth, far right or left beliefs, Irish independence, anarchism, animal rights etc etc etc). He's not left a manifesto, not been in contact with associated terrorist groups, not made any political or religious statements before, during or after. He apparently has one document that could be linked with Isis, but that document was one of many that spanned a whole cache of engagement with violent and extreme materials.
Surely you can understand that point?
