Oh! Are you one of those people who object to Jews coming to live next to you because it leads to "ghettoisation" ?
I'm not, we almost had a large community of Hasidic Jews live within walking distance from my home, objectors said it would lead to ghettoisation, whatever that is.
Unfortunately the objectors won. 
I was very disappointed, I would have loved some Jewish neighbours even if they kept to themselves.
Unfortunately I think both you and the NSS have some very unrealistic expectations of sections of our society which is going to cause more resentment, rather than less.
You really do need to try and see the other POV before you start inflicting your ideals on them.
Attitudes like yours just get used by extremists as ammunition.
Blimey you really are losing it now.
No I don't object and actually I have lived in areas of north London that have a large jewish community. Currently (I fully accept) I live in an area that has a smaller jewish community but is erasable mixed, with a large muslim population nearby. Certainly very mixed considering it is a pretty affluent area. And I work in one of the most diverse melting pots in the country if not europe.
And no I don't like mono-cultures, I like to live, work, socialise etc etc with people from all sorts of backgrounds and indeed that's what I do.
And no I don't have unreasonable expectations at all. We've had a problem over the past few decades with successive governments pandering to a multicultural agenda, which was never what I consider multiculturalism to be. Effectively the agenda promulgated was one where groups (often defined by religion or nationality) were supported in living completely separate lives although maybe within a similar geographic area, so that the did not interact. And a key component was effectively separate schooling.
That's not multiculturalism to me. In my view multiculturalism is where interactions are supported and over time communities evolve as they take on aspects of other communities. And in doing so that interaction is much more likely to be respectful and supportive, rather than the current suspicions of 'them' who are different and we don't have anything to do with.
I fully understand that some communities are resistant to this, but that's social engineering as your are very unlikely to see this kind of suspicious behaviour between a group of 4 year olds. And in the interests of individual freedoms I think it is important for government to encourage integration and to provide opportunities for the children of parents from one cultural background or religion to choose a different path for themselves as well, of course, as having the opportunity to retain that religion of cultural heritage.
That's what freedom of religion means - it is about the individual being free to chose their religion regardless of their background. It isn't about saying that a religion and its culture must be allowed to socially engineer to make it extremely difficult for an individual to exercise their freedom to chose their religion (which of course may mean choosing a religion that isn't the same as their parents, or even to become non religious).
