German political correctness: renaming streets from Stelzhamer to "Feingold"

Somehow trying to research Albrechtsberger fun Jew's Harp
Concertos led me to rabid denunciations of antisemitism, like:
https://stadtgeschichte.linz.at/media/biographien/biographie_stelzhamer_franz.pdf
The 200 year ago poet Stelzhamer said stuff like:
Jews are of "inscrutable twists and turns, a giant tapeworm,
around the organs of nutrition".
and
"Jews, in their sense of their uniqueness and chosenness,
may consider themselves birds; but we, in the conceit of
our newness and greater purification, declare them mice:
so we and they nevertheless agree that a baptized Jew is
a bat."
And?  the context?  Was it a response to as of a Bismark
who outrageously suggested that the German aristocracy
should marry Jews because they are better?  Was it after
typically Jewish comments like all of europe isn't worth
the dirt under a single Jewish fingernail?
I gather elsewhere that the poet's comments are classified
as Category Two Antisemitism in a five ranked levels of
antisemitism, requiring renaming of streets, compulsory
denunciations and praises, etc., politics already very
familiar to  Americans, and it's sad to us to see in other
countries.
