I'm not attaching any blame to either community with regards geographical segregation - I suspect it's partly organic, partly driven by economics, but has probably been exacerbated by some government policies particularly the changes to the education system over the past four decades. I'm just observing that it exists in quite a number of towns that are basically bicultural rather than multicultural, and it's quite different to more mixed communities within the big cities. It's bred a sense of otherness perhaps. But then again, these towns weren't generally those that experienced rioting this time.
But the idea of Muslim communities as some sort of enemy within is clearly widespread and those narratives are generally the true face of 'concerns about immigration' in my view.
You also have to remember that current events often plays a factor in this stuff too, along with whoever the influencers are targetting. TR and co whipped them up with a target and have been doing so for a while. Racists often use something current (in this case Asylum Seekers and a murder) to lash out at a scapegoat. Whilst not as severe, it wasn't so long ago that hate crimes against Chinese people and anyone of East Asian descent saw a sharp increase, and before that Eastern Europeans were a high profile target, alongside Muslims, Muslims get a lot of shit. But you get where I'm going?
As an extreme example, if we were to shut off all immigration to Muslim people and eject all Muslims from the country then they wouldn't be placated, they'd move on to the next scapegoat.
