The established political parties and the media have created a societal climate in which it’s no longer unacceptable to openly support Nazis. The entire political spectrum has shifted so far right that openly supporting a Nazi party isn’t a taboo anymore. Thanks to that, people are now losing their inhibitions. On top of that, the established political parties have shown again and again that they don’t give a flying shit about the wellbeing of the lower and middle classes. Of course, the Nazis don’t either, but that doesn’t matter to the people voting for them, because they are buying their propaganda, which is way too often just parroted by the media.
