In reality, they only have themselves to blame with these ethnic enclosures.
During 80's and 90's did they really allow integration?
They slotted all the coloured people into one geo graphical area and kept white areas white...So naturaaallyyyyy the coloured areas ended up thriving , setting up their own businesses and what not...Now you have ares which do not look British...or English enough...
I mean, I do not want to see England over run with sharia law , but lets face it..This is how colonization happen...First set up shop, trade then gradually get into administration (east India Company) then take over.....What did they think was going to happen when they imported cheap labour during the 60's???
