(And Russian)

Nah, just a glitch in my memory

Memories rot over time. Apparently he's not. Well, South Africans have Shuttleworth and de Raadt for this to not be a final nail.

AfD in Saxony-Anhalt

Yes, I've heard of that. I've also heard that they vary much in, eh, ideological climate in different states. So - it may be just a result of them being a populist party.

I would provide a source, but it’s in German

That'd be fine, I can't write and speak in German, but a wee bit better at understanding texts.

They speak like Nazis,

Not really, I've actually took a lot of interest in how Nazis really spoke when I was 15 years old. It was a weird time in my life, so wanted to know more closely things surely known to be evil and good to recognize evil and good in my surroundings.

(Thinking of Klemperer's book.)

"Antisemitic and xenophobic" statements are not limited to Nazis, while some specifically Nazi traits of speech I can see being more popular, but really not limited to AfD and the likes. Even here one can encounter such.

they act like Nazis.

I don't think they've started killing their opponents on the streets yet, or forming paramilitary groups.

doesn’t mean they are harmless or that calling them out for what they are would “water down the term ‘Nazi’”

You may be right, but parties and entities more similar to Nazis in other parts of the world usually were pretty open about their intentions from the very beginning, while AfD doesn't send the same signals.

Anything is worth differentiating from a thing which is, well, different from it.

Kemalists are not the same as Young Turks, for example (however, saying that Kemal and Kemalists are not a direct continuation of Young Turks for all intents and purposes is something only a clueless European would do, trying to whitewash them because Kemalist Turkey joined NATO early).

He can go to Afghanistan and offer his kids (if he has any) for bacha-bazi, right now.

Congrats, you are smarter than most people talking about regulations.

Nazis will also never come back. What, they soon are the biggest party in Germany, in other countries too?

Calling AfD Nazis is an exaggeration watering down the term.

I'm not saying actual honest-to-God Nazis are not coming back. In fact, I'm sure they are, no evil is ever defeated forever. Time to cast away stones and time to collect stones.
