That had nothing to do with "separation of church and state". It was banning private individuals to use a specific form of architecture. Pretty much any country in the world allows building mosques with minarets... did they threaten anyone's liberty / change their culture? Going back to GP's point, the deeper issue is that people thought this was worth writing in the constitution. Other countries apply such laws in different ways, so I don't think the Swiss direct democracy is to blame here.
