I've always noticed main theme in a lit of Fassbinder's works that you can seen in Ali. Fassbinder was born in the post WWII generation. After WWII it seems that the generation of Germans before him were so ashamed of what they were all complicit in letting the Nazis do that they refused to speak about it. You can see this in Fassbinder's segment of Germany in Autum when he tries to debate with his mother (who witnessed the Nazis and WWII) about politicts and it is like pulling teeth. I think what Fassbinder was trying to say was "the ideals that lead to the rise in the Nazis didn't die with Hitler and the refusal to talk about it will only strengthen these ideals and lead to another Nazi party."
