I do believe immigrants now have to do a test on 'Britishness' as part of their application for residency.
One of the problems with immigrants is unwillingness to integrate. The setting up of communities in certain areas that have little interaction with the wider societies causes conflict and resentment. Especially when distorted reports of they getting preferential treatment is reported nationally.
I have no problem with people keeping their culture and beliefs, but really it should be personal and not affect association with other communities if they are not keen on it.
When you come to this country, you should come to accept the culture here also and fit it in with yours, not condemn the host's culture as evil. You must accept that your children will eventually assimilate, and not chastise them when they do. If your major concern is adhering to your religion and culture to a T then you should not expect life to be easy in a foreign land.
I think you have been brain washed by the right-wingers. Why is not wanting to integrate a problem? This is an argument at racist use all the time. And who is condemning the host's culture as evil? Are you talking about Muslims? This maybe true of a small minority of people from a Muslim background not true of the majority of immigrants. Would you say the Hindus, Nigerians, West Indians or even eastern Europeans are "condemning the host's culture as evil"? You've taken the experience from a small minority and tarred everyone with it. The majority of immigrants , I your words, "accept the culture here". The question is do the people accept them?
Before people completely "assimilate" and abandon their culture lets take a lesson from history.
Race Riot of 1919
Many men from the empire were invited to work here during the war. Many fought in the war and had medals. After the war their employers and soldiers turned on them because they were no longer needed.
May 1919, The Times, reportsLarge crowds assembled outside the Strangers home for Asiatic seamen in West India Dock Road and attacking any man that dared come out. The police and governments solution was to try forced repatriation.
Sir Hari Singh GourIn 1941 he was refused accommodation in a west end hotel because they objected to coloured men. The government tried to suppress the story as they were recruiting thousands of Indian men to fight for them.
It doesn't matter how integrated one becomes if some objects to the colour of your skin. In our times it has become unacceptable to say you don't like someone because of their skin colour so the racist will find other reason to attack the immigrant.
So beware of the people who say it's because people don't want to integrate.
Beware of the people who say immigrants are getting preferential treatment
Beware of the people who say immigrants are taking their jobs.
Beware of the people who say there is too much political correctness.
Before you attack the immigrant please consider how welcoming people really are to immigrants.
The Left and people like Jonathan Harker are condemning the host culture and you posted his article with out criticising it so I suppose you agree.
Not wanting to integrate is a problem, it's not a massive problem like the Daily Mail makes out but of course it's not good.
A_G you are lost in paranoia and the madness of the Left, like a McCarthyite seeing commies under his bed you see racism and right wing oppression behind every comment.
People like you use the doctrine of the politically correct like a battering ram to close down debate and demonise anyone who says things you don't like.
The fact that you had to search for historical examples of racist mobs and open discrimination (1919 and 1941) should tell you something about how Britain has changed for the better.
Why didn't you just remind us of the regular murderous rage of the white racists that spills out on to our streets today? Oh yeh because it's not happening is it.
There is not an oppressive right wing state and the population isn't a seething mob of racist nutters.
Britain is a liberal democracy with a liberal politicians and a pretty tolerant multi racial society.
Get over it try not to stereo type British people and don't throw the accusation of racism around without a bloody good reason.

I could give you numerous historical examples of pogroms in the Arab world, serious sectarian riots in India and tribal/racial genocide in Africa that are still happening to this day but I doubt you would allow me to use these examples to accuse the people of these countries of being racist oppressors.
I suppose you think the problems in these countries are all caused by European imperialism anyway.
There really is no balance on the Left.
Beware of those who use accuse people of racism at every opportunity.
