I agree with so much you write.
What is interesting though here about the difference between secular and non secular Islamic countries, are that places like Albania, Kosovo and the Five Stans are all ex communist states, and communism as an ideology doesn't tend to accept religions as part of their political systems! But having said this, I have also met and worked with plenty of non radical Islamists as well, so I dont think all of Islam is necessarily extreme!
I also think its interesting to see how extremism and cult behaviour, thinking of now, but also of Europe in the 1930s, eg Spain, Germany and Italy, and of course the USSR, seems to get worse at times of political and economic stress!!
But yes of course the government, should be exploring extremism from all directions a lot lot better.
Its easy to have systems like PREVENT to safeguard children, but as was made obvious by Axel, whatever his name was, this system, even if children are reported to it, isnt that thorough or have enough power to do that much.
The Koran is pretty extreme in parts. The Prophet Mohammed (PBUH) started off being pretty chill and only attracted about 100 followers, then went extreme tribal aggressive expansivist, conquered Mecca and Medina, killed all the pagan Arabs and launched a mass following based on promising his followers booty, women, slaves and riches. It's mad stuff. Then again, Kings 1 & 2 in the Old Testament is mad stuff too. You wanna know what the ancient Israelites got up to? Child sacrifice, mass murder, it's all in there.
My point was more that there are many countries where the majority are Muslim and yet they're thriving economies based on the rule of law, women aren't oppressed and abused and no one thinks martyrdom, slavery and conquest are good ideas. The key for me is not the religion itself but how it's practised. Separation of state government and religious practice, imho, is VITAL for any country to develop into a first world country.
Take India, the chauvinist Hinduism practised by Modi and his followers is oppressing the Muslim population, is violent, backwards and deeply misogynist. For me it's about religion allied with political power, that's the deciding factor.
re: Communism, Facism and National Socialism (the latter is not the same as Facism and it drives me nuts when historically illiterate people elide them). I think it's telling that the twentieth century was probably the first totally post-Christian century in Europe and European Russia. Europeans thought they were so enlightened, embracing science and leaving fuddy Catholicism and Lutheranism behind. And what happened? The twentieth century turned out to be the bloodiest, most violent century ever known. Europe got rid of Christ. But their new religions - Communism, Facism and National Socialism - turned out to be far, far worse.
Religion allied with power can be a force for evil, as in Iran. However, religion, practiced in good faith and compassion, can be an important modifier of humanity's worst extremes.
We dismiss all religious faith at our peril. Equally perilous is practising faith blindly, chauvanistically, and seeing non-believers as less than human.
TDLR: Humans are complex and sweeping generalities are meaningless. Who'da thunk it?
