Sure, but chavs aren't really feared much - there is little of the scary 'other' about them, rather they the other that differs from us only in style, taste, class, and education. You don't bolt your doors against chavs particularly, you sneer at them.

Becks and Posh are the King and Queen of the Chavs. They and their fans aren't feared, and the media loves them - but they sure get sneered at a lot.
