There are large pockets of the UK that have zero British nationals. This means that individuals who moved here, lived here, never became citizens. My local GP has to have doctors that can communicate in Urdu because people don't know English. There are Muslims who, when celebrating Hamas' actions in London stood on statues, tore them down in the past, and in general, just disrespect our own cultural icons. Is it really hard to imagine that a group of people who are here solely for economic benefits have no love or loyalty to the UK? On top of anecdotal evidence, you can look into the many scandals that the police cover-up, with Rotherham being the major one.
They are not integrating, they are expecting the country to bend to them. Go to BHX airport and the majority of the signs are in Arabic because the people cannot speak English. Knowing the language of the land is the first step to integration, and many are failing at that.
But once again, call the concerns of natives as racist. It's easier than admitting that there is something sinister going on. It's why people across Europe are getting fed up. A pensioner in my country was stabbed to death by a "refugee".
Maybe you don't get it. Maybe you just feel it's just. Maybe, just maybe, you want it to happen. I wouldn't be surprised. The amount of anti-White, anti-native against Western populations is staggering.
