It is not yet known how many anti-Semitic crimes the security authorities recorded in Germany in the past year.
But one thing can already be said: the dark field is likely to be many times larger than the bright field known to the police.
With more than 2,300 criminal offenses in 2020, this in turn was greater than at any time since records began in 2001.
The latest situation report on anti-Semitism by the Federal Office for the Protection of the Constitution does not suggest that there will be fewer in 2021.
Because not enough with the hatred of Jews and the state of Israel, which serves as an identity marker for right-wing extremism and the various Islamist currents.
The policy to contain the corona pandemic led to a renaissance of classic anti-Jewish delusions, flanked by absurd comparisons between state protective measures and the persecution of Jews under National Socialism.
These variants of anti-Semitism will probably not have a long life.
However, as right-wing extremism gains strength, an increase in political and racist anti-Semitism is to be expected in Germany.
This has long since turned from an abstract to a concrete danger to life and limb - and thus to all of us living together - see not only the attack in Halle.
