> [...] to the second most popular party in the nation
The Afd came in fourth in the last election (European Parliament, just about a month ago: https://en.wikipedia.org/wiki/2019_European_Parliament_elect...) with 11%. That's a far cry from taking over the nation, and they seem to be past their peak.
I also don't get the logic how strongly condemning the Holocaust is supposedly a reason for their success. How is your neighbours not loving the flag any justification for hating foreigners, women, and the free press?
Anyway, there are many other countries without Germany's specific history, a long tradition of jingoistic patriotism, and still they have far stronger far-right parties today, i. e. France, Austria, Hungary, Italy, Poland, Russia, the UK, Finland, Greece etc. etc.
