Except this isn't any excuse but very publicly available data. Most of the people voting AFD were non voters before because no one pretended to care about their local issues.And again, none of this is an excuse to vote Nazis. It is, indeed, very fucking comparable to the US 2016 elections and the bullshit excuses Trump voters made up.
People need to stop culling every argument of these people because they voted for nazis (I'm a green voter myself). They have very real issues non of the established parties cared about solving (Not that the AFD will do it but atleast they pretend to listen).
We had the same arguments a decade ago when east germany voted Linke and everyone freaked out and was calling east germans communists.
