A world of memes comes crashing down on our shoulders: peacemakers versus terrorists, freedom fighters versus extremists, progressives versus what we assume to be regressives. It's important to remember that a word has no meaning unless it is the true name of something; someone referred to as "evil" may be anything but. The most dramatic term of our time is "extremists," so we should inspect and see what it actually means.
An extremist, in the current parlance, is someone who disagrees with "modern society": the combination of industrial capitalism and personal liberty in democratic systems that defines the progressive West. All of Europe and North America and most of their allies have some variation on this type of system. Even further, it is upheld as the reason to support the West in its crusades: we bring you "freedom" and a nifty product-oriented lifestyle.Extremism
