Not sure what you're referring to by "authoritarian", but gas tax raises were in the Macron presidency platform during 2017 campaign. And let's face it: people would have never care that much about those taxes if the overall oil market was down in the previous month.
The problem with these broad questions, is that:
A: The result includes people who have "sympathy" for the Yellow Vest
B: Taking a side doesn't cost anything. Some people says them want more money? Oh yeah, i have sympathy for them, why not...
My problem with the Yellow Vest "thing" is that i'm hearing a lot of people saying they don't usually vote because they are "apolitical", claiming that THEY ARE the people, saying they want plenty of contradictory things right now, and when someone try to articulate an answer, pull the magic card "people doesn't understand what you're saying". And i have already reported earlier about their authoritarian behavior.
Not that Macron didn't deserved to be bitten back after showing quite some arrogance, even by french standards...
The both funny and sad part of the article is that this woman, who for a living used to chase ectoplasmes, has a particular taste for conspiracy theories, and has just set a small sub group (The Free Yellow Vests) with two figures having far-right social history - one of them having been a candidate of the last parliamentary election and ending last with 0.6% of the votes.
