The racist behavior and hate are indeed a huge part of the problem. I believe you when you say it's escalating, however this one is relatively well known and not specific to France.

My feeling is a bit broader than that : we're entering a generalization of violence at every level of the society, including the state. This last part is the one that worries me the most, because state is supposed to be a cooldown actor.

What happened on the contrary, is that macron's government has decided to "show action", and "tacle the real issues of the country, without taboos". Which may have started with a good intentions, but is turning into a mess of laws turned against the people, mostly in the form of population control.

To me, to most striking example was what happened during covid with lockdowns, and public shaming. And the worst is that the population generally agreed because it was "for the people's own good".

Same thing is probably going to happen now. They'll strike with a new set of measures attacking public liberties, but since it'll be presented as anti-riot measures, the population will probably accept them.

Note that this isn't particularely new. The US set the examples with post 9/11 laws that basically threw the constitutionnal values to the trash provided it was vaguely presented as helping fight against terrorism.
