The divisions here run along the class and cultural heritage lines. You live and work mostly with your peers, but interact with people from outside your groups a lot. The population density is much higher in UK (and Europe in general), and we have a lot of migration, so it is difficult to construct a boogeyman out of a whole cloth.

I would think that people feel that the way outgroups go about their lives is bonkers, but that most of the ingroup people are crazy in their own right.
