Yes we did, but I think that the people who needed it the most, were the ones who either didn't had to read it (the ones not in a "lycée général") or whent through because it was required but didn't tried to understand the meaning.

More broadly, as teenagers, most of us didn't had the maturity to truely grasp the meaning ; and the ones who did probably already where sensitive enough to don't fall in the same traps.

In the hundreds of people I crossed path with during my school time, I don't remember a single one who was actually enlightened by things in the program. The only ones who had kind of a shift from their original mindset did that outside of school or because of a teacher who went out of their way (and of the official program) to explain things.

Odd things can enlighten someone. I was outside a gay bar in Avignon when a guy I knew who was hardcore FN hesitated and then sat down next to me, a Jew, and had an honest conversation. I think it doesn't take too much to enlighten French people, because much of the template for plurality and tolerance is already there and built into the culture. Then again, there are always some true assholes.

I don't think I was enlightened at that time, but at least, we discussed these topics and they are part of the collective knowledge in Europe. It's probably why Musk nazi salutes resonate differently in Europe vs the US. That being said, populism is raising in Europe too.

Is "The Plague" considered an allegory of the struggle against upcoming extremism?

While reading it I saw some parallels with occupation: people trying to escape, some suffering from being separated from their loved ones, those abusing the system and enriching themselves with contraband, help being flown in irregularly, etc. But I didn't get as far as Nazism.

Do you happen to remember which elements supported that supposed theme?
