Roger Waters has been wearing that uniform at least since 1980's [0]. He becomes a fascist to criticize fascism not to advocate. It's like trying to cancel Charlie Chaplin for becoming a Fascist.

Back then he wasn't a critic of Israel and therefore nobody cared.

I'm a Jew and I don't think he is anti semitic. That's absurd.

Trying to distil that into something coherent - the central argument would be that Waters' show, which employs fascist iconography in pursuit of an antifascist message, is a bit near the knuckle in Berlin due to the city's history?

I mean, I guess I can see that but would point out it didn't seem to be an issue when he did a high profile, all-star rendition of the same piece in Berlin in 1990[0], and also he rejigged the show for recent Frankfurt gig, AIUI because he came to sympathize with the point in the paragraph above.
