My next point is how the French population cannot even elect Le Pen.

You have to understand that, following the collapse of the Third and Fourth republics, the current French system was literally designed to be as moderate, robust, static and unshakeable as possible. The French presidential election favours the victory of the least unpopular and least controversial candidate, not the victory of the most popular candidate. Zemmour and Le Pen actually had more support than Macron in the first round of the election, but the second round put all leftist and liberal forces against Le Pen. And France, of course, has a presidential political system as well.
