While few, if any, are out rioting because of Macron's wife... Macron being so shallow, so mind-numbingly dumb to marry a pervert is a clear indication that many of his important decisions would be horribly wrong too and that he seriously lacks in moral axis.
Same way someone saying "I understand pervert Harvey Weinstein has some issues but he is still my best friend!" is someone that would make horrible decisions as a prime minister, so is someone that says "I think an adulteress that abandoned her husband and kids for her underage highschool student is a person I want to spend my life with" is someone that would make bad decisions as president of France.
And those bad decisions led to the current unrest. Those bad decisions could have been avoided if progressives weren't all going "oohhhh, an unconventional couple of a cougar and a homewrecker teacher's pet! " and have never elected Macron to public office, let alone the presidency.
In the end, you can't expect from a fish to fly and you can't expect from a man like Macron to make good decisions.
