A large part of your evidence is that “far-right” parties, like the Sweden democrats, are growing. But ~none of the western parties you mention are running on an explicitly anti-democratic platform, which was a fairly unifying feature of the worst dictatorships throughout history. “Marine Le Pen is a fascist and will start democratic backsliding if she wins” is a pretty odd assumption to just leave unsubstantiated.
