Al Qaeda, Al Shabaab, Boko Haram, the Taliban, ISIS - it's fascism with a religious flavour, and fascism is always a danger. I'm not a fan of any religion but, as pointed out by progressive Muslims, Islam has not been through a Reformation nor an Enlightenment. The Arab Spring seemed like it might be the beginning on the Islamic Reformation but it now looks like it has fuelled a reign of terror.
I don't think the comparisons with Northern Ireland or the right wing of the GOP are helpful. It is just false equivalency. The religious right in America may have some unpalatable views on gay marriage and abortion but that is not the same as burying children alive because their parents didn't convert. Irish paramilitary groups did some heinous things but there was never the sense that their ultimate aim was even scarier than their terrorism, as there is with ISIS.
Somebody said earlier on this thread 'This is not the Nazis'. Well, I was watching a repeat of The World At War earlier this evening and it was chillingly familiar. I had seen the episode before and what struck me this time was the parallels with ISIS. They are not the political establishment, like the Nazis, but their treatment of civilians, the erasure of whole dissenting villages, is exactly comparable. I find it disturbing that some are questioning what ISIS are doing because the same doubts were raised about reports of persecution at the beginning of World War II. We have seen footage of women and girls being sold from cages, we have seen people being beheaded with small knifes, we have heard surviving civilians talk of crucifixions and live-burials, we have heard the words of ISIS themselves.
Russia has also been mentioned on this thread. I think the turn Russia has taken under Putin is a threat but I think the difference between the Islamic State and Russia is that the former has no fear of mutual self-destruction. If ISIS gets hold of nuclear weapons, biological weapons and dirty bombs they will use them because their own people are expendable and the whole point is dying for the cause.
I remember studying the Reformation at school - auto-da-fés, the Inquisition, witch-trials, it all seems so distant. I can't believe this shit is coming back so strongly in my lifetime. Why can't the Middle Ages fuck off and leave the rest of us to become more like Scandinavia? I want progress not a bunch of fascist blokes doing what fascist blokes have always done.
