I disagree with OP here. Hitler absolutely rose to power due to having the support of a plurality of Germans. This isn't a case of "too much democracy," however. It's a case of "German society was systemically antisemitic and racist and happily voted in Nazism because they wanted it."
Germany was not uniquely anti-Semitic compared to most other European countries nor was anti-Semitism their main appeal to most of their voters (as opposed to a core base of ideologues and true believers).
This is true. Wilhelmine Germany in the early 20th century was fairly tolerant of Jews; it was not Germany but Russia that was the home of terrible pogroms and persecution. My great-grandfather was a German Jew who served in World War I and won medals (the Iron Cross), something that would not have been possible for the Russian Jewish side of my father's family.
