I don't care if "quite 100%" of unionized people are in unions that were against the pension law, it doesn't tell anything reliable about their support. They mainly followed what the union told them. Same with polls, I don't care what they say as they are easily oriented, interpreted, ignored or promoted depending on opaque support from influential actors.

If only there was a reliable way for people to express their support and have some influence on who gets to rule... Hmmm, like votes and elections, maybe?Maybe we could call that democracy. We would equip it with super-rules, aka a constitution, that would define "democracy" with actual laws. Using the laws from the constitution isn't "twisting it". The ones doing some twisting are those who provoke massive outrage about something perfectly constitutional. There was a vote ultimately (actually several votes), called motion de censure, and the deputies against the reform couldn't form a majority. And I don't care it was only missing 9 votes, all the rules were followed. If you don't consider the rules should be the decider, then rules are meaningless. Then why bother with a constitution?

It's nice trying to think about how the constitution could define democracy differently that in the current one, but if you think that polls and unions should be part of the definition, it just doesn't make sense. The 5th republic was a response to the political instabilities that plagued France in the wake of the 2nd war, probably not helping France get a consistent stance against Nazi Germany. I don't see why it's attacked today, apart from some opportunistic reasons from actors with questionable and vague alternatives.

You are bundling many weak points together to make up for an actual strong one. "Many people are afraid to protest in France now.". Really? That's somewhat funny because according to unions, millions of people recently protested in France, for weeks. Are you sure you're not confusing with Russia? Protesting in France is not going anywhere, and outside of some twitter disinformation campaigns, people are more afraid of bad and violent actors mixing with the protesters, breaking and burning stuff, provoking police, than the police itself. Of course police is also guilty, their response can be completely inappropriate. But even then, is that because Macron is president? Do you think he personally orders the police to be violent? Why? I don't think he has anything to gain from increased police violence, as it's used against him by his political opponents. Attempts at forming a police brigade specialized against violent actors is possibly counter-productive. But what are you supposed to do when hundreds of people determined to burn something down for whatever political reasons are exercising power from violence and intimidation? And completely free from consequences? Are a few hundreds of radicalized people going to dictate what is allowed in a whole country? I don't know what the response should be, but it can't be giving up or blaming police every time.

Finally, I'm not sure where you heard about pressure against journalists from Macron, spying laws against them, or "terrorist" laws, but I'd be curious to know.
