Making up British values

Last March I wrote in Liberal Democrat News:

The problem with today’s world is not that terrorists believe in their cause so strongly: it’s that the democracies’ belief in theirs is so weak.

In today's Guardian Timothy Garton Ash quotes a 22-year-old Muslim woman from Leeds to similar effect:

"The bad thing, and I don't know how we can solve this, is that they [the British] don't really know what their values are. So when they are attacked they kind of seem to be making it up."
