Such a claim is obviously wrong, since in Switzerland we have a great many parties with all sorts of political positions, not just two. To divide the political spectrum into only "left" and "right" is an oversimplification. Switzerland still has a healthy distribution of the population across the political spectrum, and it regularly happens that so-called "right-wing" parties advocate left-wing issues and vice versa (as can be seen again in the last vote). As in the USA, however, academic dellusion is also spreading in this country; I recently found this video which has a good explanation for this phenomenon: https://www.youtube.com/watch?v=5Peima-Uw7w (Why Smart People Believe Stupid Things).
