Correct hence trying to come up with some western secular kind of Islam will never work.
Not every Muslim will practice and many live a secular lifestyle however to try and some up with an Islam where the actual text becomes secular and a political Islam doesn't exist is doomed to fail.
It's impossible for a learned scholar to validate such a thing.
Mate, you're convinced of this, and I've heard this plenty of times from other Muslims, but that's the atmosphere, the setting you've known always. I'm sure for every other religion, there was a point when it seemed complete adherence was non negotiable. Hell Hinduism is considered fairly flexible these days in a lot of countries (not all!) but there was a point in history when people killed each other en masse over their chosen fairy superhero avatar hero saviour.
The collective mentality, will of the people shapes everything else. If the overriding mentality in a certain area is shaped by a secular education, understanding, then you can work the details of religion to suit a healthy way of life. If the mentality in a certain area is shaped by poverty, heavy focus on the Way (whether it's Christian, muslim or otherwise), you'll get your head kicked in if you went in there and suggested a better method. The mentality of the people comes first, and to have the best possible quality of people, you need to let them have 1) open access, 2) a good level of secular education, and 3) complete dialogue, discussion, analysis. 4) fair living conditions and opportunity for advancement
Now tell me which Middle East country can honestly claim to have all four. The issue isn't in the UK, you can talk about the value of life to the young morons in UK mosques all you want, but if they're set on wrecking shit, they'll only ever see you as second class material, with the real source being the peninsula. You can't get through to them. The path, for them to think a certain way, has to be obliterated. That can only happen at the source. Until then, you'll continue having the attacks, the fear, the pointless discussions.
All the while propping up middle eastern monarchies that preserve themselves by keeping their citizens at a low level, preventing the creation of a better mentality in the people overall (rather than in pockets which of course will always exist), keeping the ground fertile for those who a preach a non-negotiable Way. A continually existing Way, which of course morons globally are free to tap into because they want to fuck shit up.
