For context: dissolution of far-right groups in France under center-left government, or generally before Macron were rare since the 90s. The reasons :
- trying to kill the president (under a right-wing president, when right-wing didn't actually meant authoritarian),
- actually killing someone,
- terrorism (found bombs and shit).
Dissolution of right wing groups under macron:
- massacring gays around the pride parade (OK, that one is deserved),
- fighting,
- training,
- pretending/performative art (it was quite funny actually, I don't think it was on purpose but we laughed a lot)
----
Now, the reality about the 'left up in arms' having no problem with authoritarian government and calling the police:
A left-wing media was dissolved in Nantes for giving informations about when the next protestation will happen (basically). Also they explained how to transform a fire extinguisher into a paint bomb, which isn't nice, but I mean, they weren't militia at all.
'funny to see the left up in arms'...
Left-wing people in France called out macron authoritarian drift way before regular conservatives, way before that
I think the facts are a bit against you. Your idea seems pleasant at first glance, but fail to meet reality. I thought it was a new trend, but I read a bit recently about political theory, and one fascinating things was that some political ideologies are declined from example and experience, from material conditions, and from that is drafted an ideal. Other are declined from an idea, then try to explain why the reality doesn't work like that (it's often because of the francs-maçons or the jew, but sometimes it's internal traitors).
I will let the reader guess which ideology is which.
