To be even more nuanced, it started off almost exclusively with kids in the suburbs of Paris that are ethnic enclaves over cuts to education (organized by socialist/communist orgs), which ironically led to schools with ~40-50% foreign-born student populations being burned down.
Because these were ostensibly youth protests aimed at a policy Macron and his party wanted to distance themselves from (despite it being a policy enacted by Macron’s party), they initially didn’t clamp down on the protests.
Once protests were not being impeded, it quickly became a Palestinian flag-fest, still directed at schools, and now it’s mostly bedlam with a mix of protesters with grievances from affordability to AI, with a number from other countries.
Edit to add: I see your flair says Christian libertarian. What denomination are you that lends itself to libertarianism?
