Let's do this, I submit to you a somewhat "particular" writing by Schumann ... pity it is little known.
In my opinion, there are the prerequisites to classify it under an anti-Semitic key:
http://www.rodoni.ch/schumann/scritti.html
In essence, Schumann ventures into a forced (if not partisan) comparison between two works that have absolutely nothing to do with one another, and yet, using subtle and clumsy dialectical means (see the leveraging of the fact that the two works were written in the same year, something he himself reiterates to muddy the waters) to give us a big "tall tale"
"the two most important compositions of the time"
(the Paulus is a youthful work by Mendelssohn and, as praiseworthy as it is in certain aspects, has nothing to do with the importance of the composer's true masterpieces, such as Elias, for example; at least at the time, the importance of one and the other composition was absolutely incomparable)
In reality, the comparison was written ad hoc to disqualify the heretic Meyerbeer in front of the "convert" Mendelssohn.
Besides this, it is interesting to note how Schumann, in dealing with Meyerbeer's work, understands absolutely nothing of the accumulation of genius contained within it. For example, the device of the Marseillaise, a true subliminal message ante litteram, or that of the Lutheran chorale transformed into a cry, and many other things.
Of course, these are all things that, to be truly well understood, would need at least a century of aesthetic maturation, against much contemporary cultural resistance. And so I cannot help but notice how even atheism can be a strength in artistic creation...
