I am not equating people and nation states. I am comparing ideologies and statements that express sthat ideology.

Now whether Scholz lied when he made that statement is another question, and as you point out there is good reasons to assume so. But the statement itself and also the "role model" that it is giving to the German citizens is highly problematic for the reasons i gave.

And with that it feeds into a larger ideological problem of Germany in the context of Israel, where jewish people protesting against the Israeli bombin in Gaza are taken into custody, and jewish demonstrations are banned, citing "likely antisemitism" as reason. Jewish people, Palestinian people and other critics of the Israeli government are excluded from political discussions and cultural events because of their stance on Israel or openly discussing topics such as the Nakba or crimes commited by the IDF and settler terrorists.

So even if Scholz lied, when he claimed "solidarity beyond all questions" it is setting dangerous precedent to continue the exclusion and sometimes persecution of voices critical of Israel in particular jewish voices critical of Israel. And this is really important in the context, that you said to be relevant. A big part of the context, and also what Erdogan claims, is that Germany has a special responsbility stemming from the crimes of the Holocaust. But instead of seeing that responsibility towards all jewish people, this responsibility is only seen towards Israel going as far as excluding and persectuing jewish people in Germany, who dared to voice there opinion. Germany is commiting antisemitism, claiming to fight antisemitism directed at Israel.

So i draw two conclusions: Germany does not care about antisemtism and it doesn't care about the jewish people, aside from abusing them as a token of "look how we changed." The historical context gives a convenient leverage for Israel over Germany and it is particularly practical for Germany to avoid questions of needing to be critical of Israel and evaluating problems when it comes to export and import of military equipment, surveillance systems, trainings etc.

For a more in depth explanation as to why Germany doesn't genuinely care about antisemitism and what position towards the jewish communities in Germany the government takes, i recommend this exhaustive article:
