Fear of the mob?

In Alan Clarke’s stimulating history of the Conservative party he argued one of the driving forces behind it and its supporters was “fear of the mob”. Newtown Emerson questions the wisdom of using the social housing requirement on private developers as a means to addressing the growing housing needs in Northern Ireland. While accepting the success of such mixed developments elsewhere, he argues that many new private developments have no community identification (regardless of a community mix or not) and that the 20% requirement (if built on the same site) will lead to branding of entire developments. Is this middle class conservatism “fearing the mob”, or another attempt to define sectarianism as the reserve of working class/’social housing type’ problem?
