2. His hate of Jews could have been a result of propaganda he himself was fed early on in life, especially as to why Germany lost WW1.
Here it is wrong. Hatred of Jews was wide spread in all countries. It was not a "Hitler" thing only. Churchill had anti-Semtic views and most countries had laws and rules that discriminated against Jews. Some of these laws/rules actually continued after WW2. Jews were the go to scapegoat for centuries. Only blaming Germany for having such views is rewriting history. The whole racial purity idea that the Nazies went with, was in fact invented and practiced in the US and Sweden long before Hitler came to power.. hell almost even before he was born.
3. He may himself have been a Jew. He most certainly could not prove he was not one, since he had no idea who his paternal grandfather happened to be.
Irrelevant.
4. Germany did get a raw deal after WW1, and the allies definitely exploited the little country in a very inhumane fashion. At the very least, he had a right to hate France, US and England.
Yes she did, and that created hardship. The 1929 crash did not help either. National pride was hurt and when nationalism spurs its evil face because of economic hardship, then there are problems. Just look at today.. there are massive amounts of similarities to the conditions that made Hitler...
5. The part of Poland he attacked had always been a part of Germany. It was land stolen by France, England and the US which was then given to Poland.
Correct.. and that was deliberate... idiotic but deliberate. The Prussians were the main powerbase of the 1871 new German nation so they had to be "delt with" to curb Germany. Problem was that the Prussians were not delt with, just made homeless which caused even more animosity and became a fertil ground for Hitlers rise. A funny fact is that the very Prussians that the Allies tried to hurt after WW1 were the ones who in the end made the rise of Hitler possible and that actually survived after WW2 to form what we then knew as West Germany.. ironic no?
6. Communists. The battle to keep communists out of Germany began almost immediately after the Russian revolution. Back then, most people in that region saw communism as a Jewish thing. There were several armed confrontations between communists and right wingers in Germany during the two decades between wars.
Correct. But it was not only in the region, it was world wide. Basically Jews were blamed in most countries for all the bad things. Communists were a threat to the conservative establishment and even the newly started socialists and it was easy to link the communists to the already hated jews. It also helped that Lenin and others in the Bolshevik revolution were at least part Jewish.
7. Hitler really was a socialist. A national socialist who hated capitalism, which he considered another Jew thing.
No he was a nationalist and populist. His policies were all over the place. If he was a socialist of the time, then he would have been for state ownership of all industry. That did not happen.. in fact industry was rarely owned by the state directly but by loyal party members/supporters who basically were for the most part, part of the old conservative establishment around the Kaiser. These people in some cases were also allowed to keep their fortunes after the war and their dirty deeds and products still exist today... BASF, VW, Mercedes, Thyssenkrupp and so on.
8. He was a gifted speaker who was used by the German Right after WW1 to persuade people to hate communism, and by default Jews.
That he was. He had help, but he was a very gifted speaker. It also helps when he spoke things that were simple (blaming Jews and communists) and that people understood. You see it in how Trump does his talking these days.
9. The WW1 vets loved him. He was a hero who spoke their language.
Of course they did. The German Army after WW1 was villainized for the defeat, and the Generals whos fault it was were given a free pass basically. The fact the allies demanded that Germany dearm also did not help at all. Many were also Kaiser loyalists (until Hitler came around).. including Hitler himself. They did not want to get rid of the Kaiser and certainly did not want the socialists/communists to change their society. They were for the most part highly conservative, Christian and nationalists.
10. Hitler understood that to build a national coalition you need a common enemy. Jews served that role.
Exactly...and it would not be the first time nor the last. It is even happening today.
