More French people agree with fascism than you think, or at least according to my friends who live there, it is not something explicitly shown, you can only feel the strong undercurrent by interacting with the people there over the years.

I have long suspected that the left coalition only won because the far right was set to have a landslide victory, and because the French doesn’t want to be seen as directly supporting fascism (they want to be in a situation where they can say “oh look we tried our best to stop it but we still barely got beaten by the far right, that’s how our country end up in fascism”), some of them voted the opposite as a “protest vote” thinking that the far right would have won anyway. The problem here is that when enough people think the same, you actually end up costing the far right parties their election.

But these people’s hearts were not on the left to begin with, so they’re fine with what Macron is doing with aligning with the far right.
