Honestly....if we could expect third world immigrants to make our Europe a better place there wouldn't be such fears or insecurities as you call them.
The everyday experiences speak another language. Only with alot of good will someone would be able to oversee all that downgrading of property and land and social environment happening wherever immigrants gather, where natives flee, where ghettoes are being build.
Do you honestly think this "insecurity" is of fear the black man is being smarter???
And do you know that between those who voted against the minarets in the Swiss referendum are proportional more women than men? They have to fear the most from a islamic power, if you call that insecurity then so be it.
But in Germany there is a point of being fear of immigrant violence...that much is true.
Most of the most brutal senseless acts are done by immigrant youth...even the german media can't help it but report it as it is.
but not OK when they want to have a piece of the pie.
It would be okay if the long term development isn't pointing to downgrading of the UK to their level.
Who will bake the pie if UK becomes like a third world country? Where will they immigrate to next?
Whats the alternative? keep them segregated for ever?
Control the immigration even more...let only people in who will really be an asset to the society and who have already proven that they are willing to accept the main native culture and customs and want to integrate.
Chuck out immigrants who won't integrate!
