Peter, I know your interest in pursuing this conversation any further is limited,

One wonders about the Left's endgame, though. They clearly despise western civilisation; they have stripped our society of decency, and values, and imported a horde of Visigoths to rape and kill our citizens, but what is their ultimate goal? Surely they will have achieved only a Pyrrhic victory when the last decent middle-class male is dangling from a crane in the medieval hell-hole which used to be London? What do they have to gain?

Self-negation. They hate themselves and - by extension - the society whence they sprang. At a truly fundamental and almost unthinking level they believe western civilisation to be inherently and irredeemably corrupt and evil. It's not that they don't like it, it's just that their ideology and education tells them that it's wrong and bad. It therefore follows that anything that destroys that evil is an axiomatic good - even if the belief system that underpins it runs counter to almost all of their ideas of social justice.
