Sorry for the misunderstanding, I thought your 'why should...' phrase was more general than learning a language as an adult. I was living in Hong Kong mate, there would be very little motivation to learn Cantonese elsewhere. Sadly I have very little facility with languages other than the willingness to have a go. The fact that I have forgotten nearly all my Cantonese, and my Italian which used to be OK is now extremely ropey through lack of use, is testimony to that. No one can be forced to learn anything, but they can be incentivised to. The bar for citizenship should be set high regarding language in my view.
Let's face it, this is, as Uber pointed out, primarily an issue for Muslim women, especially those from poor and strictly religious families. Even Cameron understands this. They may have the ability to learn, but they are denied the opportunity by the ignorance of their culture.
Did I miss a news story about swans? Please enlighten me.
Your common ground argument is a good one, though it tends to treasure homogeneity, which I am personally not so interested in. We are in a new situation, because of the numbers of new immigrants, the speed with which they are arriving and the impact they have on the localities where they live, particularly public services. In the past I would have said give it a generation, these will be valuable members of society - I remember the concern when we took in thousands of Ugandan Asians (one of our finest hours in my opinion), who singles them out now? Historically the majority of immigrants have been highly motivated to get on, and to do that they do well in education and 'integrate'. I don't need them to 'assimilate' i.e. forget their heritage entirely. Some groups, like the ultra Orthodox Jews of Stamford Brook (just about the poorest and worst educated community in the country, apparently), never integrate. Religion is always at the root of it, and you know my views on that. As long as the numbers are very small, it's of their own free will and they don't harm the rest of us, it's tragic for them in my view but I can live with it.
Your original point that we have a particular problem with Muslims is the issue for me. The EU migrants will either eventually integrate or take the cash and go home. Presumably leaving the EU (as I suspect we have to) will sort this, though we will need to find workers for certain jobs from somewhere. Many (but far from all) Muslim communities seem to lack the traditional migrant qualities of hard work and ambition and remain in poverty and ignorance for generations, even if they speak English. It's the ****ing religion. I have no idea how to tackle it, and it's driving me mad.
For people already here, for most the answer is time, which is testing for our patience. Otherwise I think we are justified in saying that the intensity of the debate about immigration as well as the impact allows us to place stringent tests and limits on new immigration. These would apply to the French as well as Nigerians. You have to have confirmed work before you come here, on a fixed term contract, and a ticket home. Getting citizenship through 'naturalisation' I.e time served, no longer works. Dual citizenship for only a very limited list of other countries, if any. Only citizens, or people who will not draw a state pension, can retire in the UK. Clear, strict and enforced visa requirements. Etc etc
I hate all of these things of course. This is a really challenging topic for me. All my instincts say one thing but I can't pretend there isn't a very real and very divisive problem, and I don't believe it is driven by racism and xenophobia in the most part. But the language and vitriol with which some of the views are expressed, including on this thread, sparks a knee jerk reaction in me.
Sorry for the long ramble.
'It's the ****ing religion' just about sums it up for me.
