I can only look to High School where one lunch a week the Christians, the Muslims and other religious groups separated in order to speak about their interests but 4/5 lunch times they were playing football with the rest of us and each other. There were also occasions where they and other groups would do bake sales introducing us to each of their cultures.
It doesn't work if immigrants are coming in with a "we're here, get used to it" attitude and there are no "lunch times" where each group can get together through some shared activity - multiculturalism or multi-cultures living very much detached from each other?
UKIP have got such interest because they were willing to talk about immigration whereas previously parties were reluctant to say it can be a difficult process, but the latter point does not mean we give up on immigration. Immigration can be so fantastic and we can look at Leicester for an example of how to get such varied cultures living together and making a City colourful and thrive. We also can't deny that expecting to support unlimited people while making such massive cuts to public spending is not going to work and is going to lead to rising tensions, but that is not the immigrant or the refugees fault. I used to make the point that any charity door knocker will tell you poorer areas are more willing to donate but I think the rise of UKIP and the drag to the right in Wales might make my point redundant.
