Seriously, what IS this cobblers?
"If you come to the UK to live then you either fund your own group for whatever community you feel part of or you join in, the latter would be better." This just sounds like some massive, sinister hokey cokey.
"This is Britain, you take the rough with the smooth...if you don't like it there's a big world out there." This could be the spoken intro to a heavy metal track and is of similar relevance to social and cultural politics.
"If you don't like British culture and people, live elsewhere." Really? So if a French person (for instance) smuggles a Sartre novel or Johnny Halliday record into the country they are some sort of dangerous activist and need to be ousted before they bring the whole system down? Why is it so important that everyone living in Britain loves the British, unquestioningly, uncritically and all the time? What will actually happen if they don't? Is there a danger that we will suddenly realise that the Empire is gone and we are, frankly, no longer anything special?
