The problem with any subject that incorporates the issue of ethnicity, is that these issues have become the new victorian equivelant of 'sex', i.e that not to spoken about.
If people wonder why resentments fester etc, it's because the public feel that they can't talk about such matters, or at least there is nowhere for them to vent their concerns, some founded and some unfounded.
By criminalizing the issues of immigration, terrorism (and it's connection to religious fanatics) they stifle the general public of venting their feelings and there is no wonder resentment festers with community pitting against community.
I think if people were allowed their say on these subjects there would be less aggravation. It's a similar situation in Burnley where the BNP has done well, race crimes have actually dropped in Burnley. Why? Because people feel that there is someone there to represent their opinions rather than getting so worked up a mindless stupid minority take physical action.
In many ways, Brucie's retorts are directly the cause of the publics aggravation on the issues at hand. SOmeone spouts an opinion about not agreeing with multi-culturalism and brucie would simply shout them dow n with a torrent of abuse as has been proved again and again.
People like Carol on the other hand, although she may disagree with what people have to say, she is actually willing to engage in debate and reason, hence at least creating an outlet of talk for people on this issue.
Basically, to sum up: What is needed to help reduce tensions amongst communities is talk.
