> If it gets to that point they will start bankrolling far right militias

They already are, kind of. The far-righest presidential candidate who was bordering on fascist in France was bankrolled to absurd amounts by one of the richest assholes in France, Vincent Bolloré. Bankrolling a militia isn't a far stretch from bankrolling someone advocating for banning non-French names and expelling everyone of foreign descent.
