"Savage" is quite a good term here, though I suppose you're right that it could upset savages. The fact that it was applied to less technologically advanced people (who often practiced cannibalism and human sacrifice -- OK as long as white Europeans & Americans don't) who defended themselves doesn't mean much. I find it a useful term for people whose religious services often include sermons demanding the slaughter of Jews and the killing of anyone else who won't convert, especially when they videotape themselves sawing people's heads off with knives while doing religious chants, whose schoolbooks call Jews and Europeans "pigs" and "monkeys." Who also say the same about Hindus and other non-Moslem Asians. I realize that because non-Western people do this many will rush to their defense and claim it's all our fault. No, it isn't. They are intelligent adults acting within their own culture and are capable of thinking and behaving independently of us. This is an example of the practice of their religion, customs, and politics. It is not good for the world and cannot be stopped by "understanding" and "kindness" which they interpret as weakness. Everybody in the world except for a few white Americans is not an east coast liberal, nor do they stand in awe of the latter.
Moslems are perpetually offended anyhow. Actually, they are not offended. This is a psychological weapon. They claim to be and demonstrate in order to reinforce the apologetic attitude we've been forced by insane pundits to adopt, and to maintain us in the habit of submitting and apologizing. It's likely anyone who doesn't see it is a prime victim. They need to realize we aren't all like that.
As for others, there is something to thinking that they may be put off by it.
I don't know what Zurzweil's law is. Technological advance is haphazard but what we often see as a backward step isn't. Wheeled vehicles when out of much use in the Middle East as the Roman Empire weakened. Camels weren't widely used till Roman times (though domesticated much earlier), but as they were more useful for crossing the desert. The Romans had to build and maintain roads because they used horses, wheeled vehicles, and walking; the Arabs could cross the desert on camels. Thus from about 500 AD till 1800 AD there was little use of wheeled transport there. It looks like a regression but it was practical to use camels till internal combustion and steam engines arrived. Similarly, Japan ceased to use guns during part of the middle ages and until renewed contact with the West; only a few were made, under imperial control, despite their early competence in such weapons. One reason was that swordfights were more aesthetic than gunfights...but likely it was because they put too much power in commoner's hands. (See Giving Up The Gun, I forget the author).
