Depends on perspective, I suppose
Why do we not also have such serious things like that for the millions of Russians who died during stalin's reign of terror?
It depends on perspective, I suppose. Not, that is, whether we have such events, but the justifications for why we don't. Presently, the two most recognized groups that suffered under the Nazis are Jews and homosexuals. This despite the fact that not even Hitler was of the master race (wrong color hair & eyes) and rumors and evidence of homosexuality among the Nazi leadership.
Hitler targeted the Jews specifically, to the tune of millions of dead, and other ethnic and religious horrors only pale in comparison to such. Also under Hitler were Catholics and Gypsies persecuted and murdered.
The case of Stalin, however, is different in circumstance. Stalin's purges were not nearly so focused. If you behaved deviantly, you were targeted. A great reflection on such ideology can be found in
Arthur Koestler's Darkness at Noon. Much has been made in the past at Sciforums, in fact, regarding whether or not Stalin's purges were atheist-coordinated holocausts against Christians, a thesis that used to be repeated here but was never demonstrated credibly, and that perhaps because such idea has little or no credibility outside Christian-supremacist apologism.
A more modern way of looking at the difference can be found in debates over the merits of the classification of hate crimes. Many people argue against hate-crime statutes on the grounds that "all crimes are the same". And, in one respect, this is true. But if I go out in a bad mood and get in a fight and beat you badly for no reason, this is obviously a crime. But what if I further pick you out as a discriminated target because you look Jewish, or I think you're gay? Why was the last guy not an appropriate target? In one case, it's a crime. In another, I am specifically selecting you in a discriminatory manner. So while Stalin executed and persecuted many in the name of the party, his persecution knew no discrimination in the sense of the Nazi holocaust against the Jews. Where Stalin persecuted religions, it was because the religions interfered with his idea of the state. I could stand up under any given regime and
give them justification according to their paranoia by working against the state. These conflicts would eventually license (in the regime's mind) my arrest and destruction. But the Jews were selected for the crime of being Jewish, a crime that most of the world has held them responsible for over the years. What did Hitler say? That Jews controlled too much money? This is symptomatic of a time when Jews in Europe were not allowed to own property and thus survived by, essentially, working with money. It is, in fact, part of the stereotype about Jews and money. Had the Jews been allowed to be equally as wretched as the next group, this situation may not have come about. But cultures have always demanded a particular degree of increased wretchedness of the Jews, and Hitler exploited those millions for a political cause that was rooted in stereotype and paranoia, and aimed at increasing his power. It's sort of a comparison:
The Jews are bad because we say they're ruining society versus
The dissenters in general are bad because they are interfering with our agenda. In either case, it's wrong. But we remember the Jews specifically because it was so pointedly specific.
Many people are murdered in the United States day in and day out, but when a man is beaten and tied to the back of a pickup truck and dragged along a road until he's dead for the simple crime of being black, or when a man is bound and beaten and left to die for the simple crime of being gay, we notice.
A crime of passion? Does it matter that you're black or Jewish or whatever if you happen to be sleeping with my wife, for instance, and I'm simply that much of an idiot that I can't figure out anything other than to hurt you?
But what happens if you're not even a factor in my life and the only reason I'm killing you is because your nose makes me think you might be Jewish, and since you're obviously Jewish, you need to be exterminated?
Therein lies the difference, or so I assert.
thanx much,
Tiassa

PS on edit: It is worth pointing out, for scale, that Jon Stewart, host of
The Daily Show once recounted that his aunt pressed him about the fact that he seemed to live without his Judaism. It's important, she advised, because "there are only 13 million of us left in the world." Perhaps it seems like an abstract point, but when the most commonly-accepted casualty count of the holocaust equals nearly half the surviving Jewish population .... Just a point for thought.)
