If scruffy protestors invade the shrines of high culture, I guess this counts as asymmetrical culture war: The Usual Grotesques
So there I was, in the middle of the opening night of Tannhäuser at the Metropolitan Opera, when the shouting started. “Climate protesters,” or “climate activists”—the usual grotesques—were shouting “No opera on a dead planet,” and other such inanities. They placed themselves around the theater, timing it so that when one was arrested, another started shouting somewhere else. I counted five interruptions, though the first press reports say there were only four; did I get it wrong? The audience was displeased; I heard shouts of shame! and even, briefly from one member of the audience, U.S.A.! U.S.A.! The management finally announced that the program would go on no matter what, keeping the lights on so that security could remove people more quickly; either the thugs were exhausted, or the remainder figured that it wasn’t worth bothering with. So we finished the opera, with too much light, and (at least for me) some nervousness at every loud noise, thinking it might be another interruption.
There have been at least two previous intrusions at operas, in Amsterdam and Milan.
Music performances of this kind are somewhat fragile--it doesn't take much to shatter the necessary atmosphere and ruin the performance. If we think this kind of asymmetrical culture war is illegitimate, how do we combat it? Without actually crippling the exercise of culture by the burden of security measures? I'm not sure there is an easy answer to this.
