Utterly impossible to tell. Europeans have fits of fanaticism occasionally. The last two was about revolution and then nationalism rather than religion as we think of it, but the four before were Christian, ie. the Imperial Conversion, then prosilyzation(sp) of the heathen nations, then the Crusades, and finally the Reformation. These fits effect different parts of Europe at different times and the last one is often still going on somewhere when the first is popping up. All this is an oversimplification, though, but a lack of Christianity isn't going to stop Europeans from acting like monsters every now and again. I remember someone (I think it may have been Ian himself) writing an essay on the effects of an absence of Christianity. Not so bad for whites, but the world is even worse if you're not. One thing I feel for certain. Religion had next to no effect on technological advancement and, unless there is another set of accidents, European gg&s will still place a white boot on the rest of humanity's neck. Imagine that boot without anything approaching a conscience or respect for life behind it. The Romans were capable of killing anyone who they didn't know and personally like. The Celts, Germans, and Slavs were no better and maybe even worse. If no new ethic system, or an less morally intesive ethic system steps up, every European nation would've been a Third Reich. The only light I see is that Buddhism might've broken in (Christian monasticism ultimately derives from it). But I'm not so sure that Mithraism or Manicheanism would've worked.
