@Typhus: I get what you mean about fostering a strong national identity, and I understand Stu when he talks of maintaining a British majority, but I don't think the aim is to "supplant" Gd, but to sufficiently nationalise a religion. Jewish services are exclusively in Hebrew, an alien language, prayer is always towards Jerusalem, a foreign city, and many British Jews like to visit Israel or retire there. However, Judaism in the UK has successfully become embedded into British life by dint of synagogues and Chabad reaching out to their communities and due to Jews largely feeling welcome here. Jews have served proudly in the British army in regular roles and in the special Jewish brigades formed during both world wars. British synagogues are seen as British institutions, not foreign imports as many Saudi-funded mosques and madrasas are seen. When the far right said "up with Mosley! Kill all the Yids!", London Jews targeted the fascists and left the wider community completely alone because they felt part of that community; they felt that they were part of a British-Jewish tradition going back to the Sephardic Jews who took refuge here from the inquisition and Muslim persecution. They didn't blame Britain as a whole, nor would that have been reasonable at all.
It's a similar story for British Sikhs and Hindus, both of whose communities contribute meaningfully to the UK workforce and are absolutely loyal to the UK. Hindu temples are very open and encourage people of all backgrounds to come in and see how prayer is conducted and the Sikh religion is amongst the most tolerant and pluralistic in the world. I think this also goes back to Sikh and Hindu soldiers serving as colonial soldiers and the loyalty to the UK this engendered in their progeny who moved here.
Islam has never been "nationalised" this way. It's a combination of Muslim arrivals being relatively recent, the nature of Islam itself and a feeling amongst Muslims that they're not welcome for various reasons. This is why it's so important to encourage the rather tentative reformist voices in Islam like the Ahmadi movement.
Stu alludes to the ghetto mentality and that's a pertinent point to bring up. Isolated from wider society, people can develop extremist tendencies, disloyalty and resentment of the majority. This is the kind of attitude fostered in the banlieues of France and areas like Bradford in the UK. However, spending more time with your coreligionists is pretty natural given the friendships and familial ties which exist between immigrants from the same community. British Jews celebrating festivals together doesn't constitute a problem, nor does a British Muslim fasting for Ramadam in London. It's when an attitude of distrust and hatred develops that you get problems. It's difficult for this kind of attitude to develop even amongst the most insular, strictly-orthodox Jews in Stamford Hill because Judaism is very clear on obeying the laws of the country you inhabit.
There seems to be a misunderstanding that because the attacker here and Omar Mateen weren't overtly religious that there's not an Islamist angle here, but this is wrong. A lot of these people have very strong religious feelings but hate themselves and feel that their own observance doesn't matter. In their warped minds what they're doing is "for the sake of the ummah" or some such bollocks. I've no doubt in my mind that Mateen prayed for repentance for being gay before he committed his crime, and I'm sure this guy repented for eating pork and drinking. In the end it's foolish to downplay the influence that jihadi websites and hate preachers have on these individuals. This is the ideological angle brought up here by MTD and Typhus--we have a potent mix of religious fervor and ideological motivation causing people to give up their lives and see non-Muslims as worthy of death.
In fact, what we ask of them is impossible. As in the Orlando attacks, and probably here, people can now be radicalised through social media and online interactions that governments are not – and will never be – equipped to handle.
I don't agree that governments can't be equipped to handle this phenomenon, we'll just have to give up a few of our liberties for this to be possible. I've nothing to hide so I'd be fine with this. The rest of the article is well worth reading and is written by a professed reformist Muslim.
