It's not new that people are moaning, it's new that we have ghettoised groups of culturally foreign people of such numbers they are having extreme effect on policy and culture. Elizabeth I complained there were far too many [black people] (I won't use the term she did); there were a few hundred.
I most certainly do not follow Farage, and I don't know what GBeebies is? Do you mean CBeebies?
How precisely do you think multiculturalism has improved British culture? What benefits has it given us that is entirely its own influence, that could not have been achieved any other way?
Now, I would say my own experience of immigration is probably more positive than negative. But I also realise that most of the benefits I myself have seen have not been dependent on the promotion of segregated cultural groups. In fact, the most negative experiences that I have had have seemingly stemmed from cultural differences rather than the inherent pressures of immigration. And I can't think of anything that has improved specifically because of the presence of a different culture.
I also realise that I am only one person, and that other people's experiences have been less positive, or even completely negative. No doubt, some people feel their lives vastly enriched by contact with other cultures in their own neighbourhoods, and others feel their lives are significantly poorer.
I am not arrogant enough to believe that because my experience is more neutral, that other people's opinions are not as valid. That way lies Reform.
