That could indeed start a flame-war
Well, the emphasis on resistance is pretty heavy in the way we are taught WWII here in France.
A politically engaged friend of mine told me a theory about this : Supposedly, there were a lot of resistants during German occupation and there were a lot of "collabos" (pejorative term for people collaborating with Germans) and after the liberation, the fear of the government was that a witch-hunt would begin. They preferred to put an emphasis on resistance hero, to depict the whole French people during the war as a resistant one, completely occulting the "anecdotal" collaborators. This point of view was strongly denounced as propaganda, especially during the 1968 protests by the left-wing.
Anyway, the image that stays in official history is that the Resistance was very active during the occupation, mainly thanks to some courageous French but also thanks to Allied support, mainly UK support, as US did not recognize de Gaulle as the leader of the France Libre until later in the war. We are taught that the resistance took a big role in the preparation of the D-Day, giving information, sabotaging nazi equipments, destroying selected bridges, etc... I believe much of this is true. We of course are aware that this is the overwhelming resources US has brought into the war effort that managed to clean the territory of nazi presence.
The thing is, from our point of view, US didn't appear in "our" war before 1944 (note that I use there a naive point of view one could have in high school) and we had already 4 years of occupation and an humiliating defeat behind us at this point. From what I read, when the implication of US in the European front became evident, the number of resistants rose significantly, making nazi presence very difficult. One known story of this time tells about an arrested resistant who managed to jump out of a window of the Gestapo and immediately ran into French policemen he didn't know for help, which he got.
If you start the subject in France, you will see two poles in opinions : the "every one was a resistant" and the "every one was a collabo", I slightly bend toward the first opinion

What I am a bit uncomfortable is that we are less taught about the russian front, where most of the nazi effort was wasted at this time and that was, in my opinion, a far greater cause of the victory than the resistance or even the battle of Normandy.
