Seit Sonntag kursiert online eine Grafik, mittels derer behauptet wird, ukrainische Drohnenangriffe auf Rechenzentren des russischen Konzerns Yandex hätten zu einem Rückgang russischer Bot-Aktivitäten bei Desinformationskampagnen rund um die AfD geführt. Dieser Zusammenhang ist bislang unbelegt.

So viel zu dem Mythos, Reiche würden wegziehen, wenn sie Vermögensteuer zahlen müssten. Es war auch nie logisch, dass das passieren würde. Wer würde schon für ein paar Euro Freund*innen und Familie verlassen? Und den Status, den gerade Reiche genießen?

But the key chart for the current debate around The Left is this: different forms of #antisemitism by political leanings (far left to far right) *in Berlin*. It is, frankly, shocking.

For me, the most telling figure from this election: parties of the center and to its left mostly traded votes among themselves. At the same time, they suffered a net loss of over 100,000 votes to the AfD and came nowhere close to matching its mobilization of former non-voters.

Es hilft wenig, jetzt die Demokratie zu beschwören. Menschen wählen keine Konzepte, sondern eine Politik, die nicht auf sie herabschaut und die ihre Lebensbedingungen verbessert, die für Infrastruktur (Gesundheit, ÖPNV, Bildung) & ein leistbares Leben sorgt. 1/4

Es ist echt bitter: Das Völkerrecht ist das, was der "Gutmensch" mal war, ein Objekt der Häme, fast ein Schimpfwort. Nur dass dies mittlerweile oft aus der Mitte heraus kommt. Wer Völkerrechtsargumente als "naiv" rahmt, macht das Recht des Stärkeren zum Maßstab. Bis er selbst der Schwächere ist.
