Ok. The way I see it, if Hitler was neither a bigot or insane, Germany would probably have unified with Austria, taken the Sudentland in the Apeasment, and stopped there. For a while at least. I think the main problem with Hitler is that he was mad with power, and was riding an ungodly huge wave of nationalism. A pragmatic leader would have known when to move, and when to hold tight. But then again, this brings us back to the old question of wether or not it would have been best for England and France to allow Hitler to have Poland, in effect re-establishing old Prussia, which England enjoyed a particularly good relatioship with. I can't help to wonder if done correctly, could Hitler have accomplished this?
If he didn't invade Czechoslovakia and the Munich agreement, instead only supporting the Slovak nationalists and the Hungarians from afar, I suppose he might get a freer hand against Poland, which might yield without the support of the Western powers. At this point Germany will have gained Danzig and the Sudetenland, and be the undisputed hegemone of Central-Eastern Europe. Hungary, Slovakia and Romania would surely all rally to the anti-Communist banner, and with some persuasion Poland and Czechia as well. After all Poland was an anti-communist, nationalist military dictatorship, and just as Romania in OTL rather pragmatically accepted realities on the ground after Germany forced them to give up Transylvania to Hungary, I think the jingoists in Poland would be to excited by the prospect of a bloody war in the east for them to stay grumpy for to long.
Anyway, I don't think you get the dynamics behind fascism. Fascism is what you get when the middle-layers (the white collars, the well-off farmers, the small business men) feels squeezed from both the workers movement and finance capital. At one hand, they feel they are getting pushed out by the big monopolists, but at the other hand they fear the supreme monopolist, the coming Socialist state, because that will definitely be the end of their existence. To solve that riddle they make up conspiracy theories how both international capitalism and international socialism are part of the same conspiracy, and then set out to ally themselves with a primarily
imagined national capital and the traditional upper-class (clerics, nobles, military officers) against the socialists. (After the fascist victory what typically plays out is then a struggle between the middle-class ideological fascists and the upper-class more old-style reactionaries. Out comes may differ, as Nazi Germany and Nationalist Spain shows.)
Of course a socialist would argue that their being squeezed out is a natural effect of the development of the means of production, and that rather then trying to cement a old and dying way of life, they should join the workers in the struggle for a modern industrial economy, but not under the control of monopolists, but instead under control of the people.
In this scheme anti-semitism works, because Jews tend to be both in the socialist camp (in their capacity as intellectuals, and due to alienation many Jews historically felt for a society that discriminated them, though the latter is of course no longer the case) and in the capitalist camp, which allows the fascists to single out one group of capitalists as the evil ones (Jewish internantional bankers), and ally with the rest (like the Krupps), but its not antisemitism thats the real driving factor. Germany would have gone fascist even if there weren't a Jew in the country, and Hitler would simply have had to hate something more abstract like internationalism then the Jews.
(In fact, if you ask me, this very process can be seen in the US today. A Christian proto-fascist movement is growing of disgruntled Middle American, seeing their livelihood swept away by the present crisis and the long-term stagnation of the Middle-Class. These people idealize capitalism, blaming the crisis only on a small fraction of "bad capitalists" (Goldman Sachs et al) in alliance with the state, and fear socialism as the plauge. They are nationalistic jingoists, have ultra-conservative social values, are full of nostalgia for a rural past and belives in a national rebirth, "restoring the republic".)
