Seize the language, control both thought and the debate:

Andrew Bolt:
‘London’s Daily Express reports:
HUNDREDS of Osama bin Laden supporters clashed with English Defence League extremists today as a “funeral service” for the assassinated terror leader sparked fury outside London’s US Embassy.
Mark Steyn observes:
That’s an interesting way of putting it. Hundreds of people cheer a mass murderer on the streets of London, but they’re merely “supporters”. Those who oppose them are the “extremists”. 
…when even a Fleet Street tabloid covering a pro-terrorist-vs-English-nationalist protest reflexively labels the latter as the “extremists”, you know we’re losing the very language in which we can even discuss the issues.
