The far right in France seems a lot more popular then you were willing to admit.
You are conflating antisemitism, fascistoid movements, and hitlerian sympathies. Those are three different issues.
* No Hitlerian sympathies in France, period. Hitler was the enemy, and all of his theses opposed France and the "French race", which he deemed inferior.
* No significant fascism movement in France, because of a very different context from Italy and Germany: our country was healthier and suffered no identity crisis. At worse we had a few authoritarian movements and a few representatives belonging to the ordinary right-wing party. They never amounted to much and would have never ruled without the Nazi occupation.
The Milice amounted to 10k people only and was despised in France. The Charlemagne regiment was equally small, many who simply wanted to fight communism and some were forcefully enrolled. As for the pseudo-coup you referred to (that only the left called coup), it was pathetically small and unrealistic, a bunch of lunatics.
* Antisemitism, however, was still significant, but in France its peak occurred before the ww1: many Jews left the new Reich after 1871 to come to France, but they were ironically perceived as Prussians and therefore enemies. By 1933 it was no longer a major political issue in France.
As for the Dreyfus affair, it is sometimes used to build an "antisemite France" narrative, but actually it was rather a matter of trust in the army (the opinion refused to believe that the army had lied) in the context of a fight between republicans and monarchists to control the army: at that time it still comprised many aristocrats and monarchists, and the republicans were trying to break that situation through meritocracy. Dreyfus was one of those officers appointed through academic merit. This affair exposed a latent but minor antisemitism, and also a more prevalent antisemitism in some groups, yet antisemitism was only incidental and aggravating in this affair.
