Other than his mention of Tommy Robinson, it is not radical or unacceptable to say "Wow, my city has changed radically in the past 20 years and is losing its identity".
If the center and the left completely reject the validity of national identity and the expectation of immigrant integration to British identity, then you leave people with those sentiments running into the only open arms left: the far-right and the rest of their agenda.
As a liberal, even a progressive in my own mind, I still recognize that completely open borders are a problem and that we should expect all people coming to a country to want to learn the language and integrate with the native community and customs. This concept is compatible with respecting cultural diversity and immigrant populations and their civil rights.
And the UK really seems to have a free speech problem. Support Palestine too much? Jail. Support immigration controls too much? Believe or not, jail.
FINALLY - I don't see how this kind of hard-fork-over-politics maneuver helps change minds in the long run. It only generates bitterness.
