The Trojan Horse story is about the use of treachery to infiltrate the town of Troy. It is similar to the use of Third World foreigners to flood England, Europe & the rest of Western Civilization, to overwhelm us, to destroy us. It is being done as I write by the Traitors who are Her Majesty's Government and Her Allegedly Loyal Opposition. They are controlled by the Puppet Masters, the Invisible Enemy who taken over using the techniques worked out by Antonio Gramsci, the leading intellectual of the communist party in Italy.
Now, in June 2014 our wonderful government has noticed that Islamics are taking over schools. They allege that they are going to try solve the problem by teaching them to be 'British' See e.g. Fears of Trojan Horse Islamist plot in a second city as inspectors move in on schools in Bradford after extremist infiltration scandal in Birmingham
Metaphorically a "Trojan Horse" has come to mean any trick or
stratagem that causes a target to invite a foe into a securely protected
bastion or space.

This is very much what
Cameron is doing to us with malice aforethought.
