It would seem that the only right wingers who make their voice heard are the lunatic fringe and this is a world wide phenomenon.
I think it is more of an issue of the failure of the "center". The people who called themselves the "center" for the last few decades have mostly been corportist sellouts. The middle class has gotten hollowed out while the rich got massively richer. All the main sources of media are owned by people who have a vested interest in maintaining this corrupt system and all the politicians are paid off. They have been able to suppress any kind of real reform to the many problems modern capitalism is creating.
The natural response is to look for a solution. Since the standard sources of information are all telling the same lies about how great the current system is, people start looking for more extreme answers. This way you get people like Trump or Le Pen in France who pin all your problems on a scape goat. It's easier to point the blame at muslims, or immigrants, or poor people. If you do that you don't have to take a deeper look at the rot and corruption of the entire economic system.
The solution to these problems is real economic change. This is why people like Bernie Sanders need to win. Otherwise democracy is in real trouble.
