Isn't he decrying the fact that not taking up arms (or advocating for) against an aggressor, such as Nazi Germany, is specifically pro-fascist, because it allows to do anything they want unopposed.
Meanwhile your quote highlights the fact that Orwell thought that being honest about the Soviet Union and its critiques in political discussions is a mark of intellectual honesty, which isn't really pro-fascist, since you can critique the United States and still be anti-communist after all.
There are some attempts to make music also sound weird, like how that Quebecois band Angine de Poitrine became popular a month ago and their music is definitely unorthodox compared to the mainstream songs.
