"Grace, I can't see the relevance of Muslim women's language aquisition to men raping and attacking women in Cologne."
I think it is relevant. The concerns that some of us have expressed regarding very large-scale, very fast migration from countries with appalling treatment of women, have generally been deflected with responses of "Yes, but people will integrate, their children will adopt modern liberal values, and the second generation will have similar attitudes towards women (gay people, Jews, etc.) to all the other people living in this country."
This kind of integration is a LOT less likely to take place if mothers are not able to speak English.
Look at the situation in places like Bradford; large numbers of wives, brought in from Pakistan, who are unable to speak English and hang out almost exclusively within their own diaspora. Do you think this assists integration? Do you really not think that the extremely troubling attitudes towards women, gay people and Jews among many young men in places like Bradford have got nothing to do with this?
As it happens, I think DC's new ideas are a clumsy tool that could lead to families beiing split up, and I would much rather see the initial requirements for getting spouse residency status being made tougher (in terms of language skills, minimum education requirements, and even things like a minimum age floor---nobody under age 23, say).
But the problem DC is trying (somewhat ineffectually) to tackle is a real one.
Societies which want to have large scale immigration while maintaining a cohestive social structure with a high level of trust, have to be very, very serious about integration--bossy, even.
It's unusual for me to defend Singapore, but one reason why Singapore is able to have high levels of immigration while remaining a very stable society is because Singapore pushes integration really strongly; there are even quotas for schools which dictate that the % of kids from any given group cannot be over a certain level, for example. If we WANT to have tons of immigration, we may have to think about similar ideas.
