I am always, without fail, delighted to discover that a certain writer or artist dislikes Wagner (Gide, for example), just as I am equally dismayed to discover that a certain writer or artist admires Wagner (Schlingensief, for example).
The same can be said for Goethe, Schiller, Hegel, Thomas Mann, and Heidegger.
The opposite is the case for Wieland, Lenz, Heine, Brecht, and Wittgenstein.
