Michael Ledeen says that you can't win a fight against an enemy you can't even name.
Over the pond, the Qulliam Foundation is trying to figure out how to talk about the dangers from political Islam and the far right. They propose a lexicon.
The section on Islam is reasonable, and it's nice to see a willingness to grapple with it. The section on the "far right" has similarly clear definitions for Neo-Nazis, but the definition of "far right" is suddenly much less clear and precise than the other definitions in the lexicon: "a far-right ideology characterised by extreme nationalistic beliefs or extreme, intolerant behaviour."
There are no wiggle-words like "extreme" in the other definitions. Islamists are those who want to impose "any version" of Islam over society, violently or nonviolently. We know exactly who they are from that definition.
So who is the "far right"? They give some examples, but examples are not definitions. Clarity would be helpful here, as I think there's a tendency to elide a lot of ordinary right wing people and groups into the category of "extreme nationalists." What's the point at which nationalism becomes extreme? Favoring trade policies that protect your country's interests? Being willing to fight to preserve your national territory from invasion? From unlawful immigration? Or does it only embrace expansionist nationalisms, like Russia's is currently?
