However, I have a 1974 Compact Oxford Dictionary in the house (and by compact they mean in comes in a mere two giant volumes with a magnifying glass so you can read the tiny text) and holocaust is defined as a burnt offering, or being totally consumed by fire or, finally, a devastation of a large number of people. The Shoa is NOT mentioned and that was just 1974.
You must also remember that back in those days, dictionaries were more conservative and slower to adopt new words, and thus, they may have lagged behind actual usage by as much as a decade. They still lag today but it's only a few years or so. Except of course of the internet dictionaries that allow anyone to contribute.
I've often said that if Hitler had stopped at just the gays and the gypsies he'd have been fine - nobody would have cared.
Well, the fact is, at the time of the war, not too many people cared about the Jews either. Although, it's arguable that many people just didn't know of the death camps (although their 2nd class citizenship was well known and no one really cared about that). I doubt even the Jews knew what was coming, otherwise they would have fled far in advance.
But we should thank the Jews for bringing the horrors to our attention, because without that it may have gone completely unnoticed. The Armenians suffered an equally horrific loss, but we don't see footage of concentration camps or death ovens and we certainly don't see many videos of mass graves. That may be because that footage doesn't exist or that Turkey has been very thorough in suppressing it, or just that Armenians aren't that great at bringing it to our attention. Well, one thing is for sure, Turkey has been good at suppressing any mention of the Armenian genocide. Now, the funny thing about the Jews is that they're blamed for making themselves the biggest victim, however, the Jews have always identified with the Armenians. I unfortunately lost the link for this, but there was to be a Jewish - Armenian genocide memorial (or something along those lines), but back then Israel and Turkey were still allies and Turkey placed an amazing amount of pressure on the Jews to ditch the Armenians. They should have ditched the Turks back then, and shame on them for that, but they did as they were asked. Now I'm happy to hear that they are taking serious steps to recognize the Armenian genocide as they seem to no longer care so much about how Turkey will (mis)behave afterwards. It's about time.
Part of that is that the gypsies had no political organization or power and they still don't while Jews ran were prominent in industry and banking and the intelligentsia.
Hitler targeted groups that were already unpopular. However, the Jews were certainly more capable of pointing out their victimhood, and good for them. We tell rape and abuse victims to speak out against their aggressors as that's the only way to fight back and fight back they must for the sake of everyone. Despite that people in society still like to blame the victim. Perhaps staying silent is a quicker and less painful way to get over victimhood, but it only helps that one victim and doesn't help prevent more victims.
