all of the things you listed make up or result from national character. besides some short interludes, for example, Japan has had the same party in power since 1955. it's a weird thing to deny the existence of. different nations act differently. it's not heresy to make generalisations, particularly in the age of nationalism when many/most people actively try to set and follow their country's norms
