Was I in the wrong

Me and my wife are in a bit of an argument because she did not like how I responded to her receiving some death threats. I can see how what I said may be considered victim blaming but at the same time, I don't understand why she did any of the things she did. My wife got into it on Tiktok with... Teenagers. Over BTS. Which I believe everyone should be allowed to have your opinion, however if you want to sleep peacefully at night there are some fandoms you don't piss off. BTS is a big one.. Their fans are insane. I also don't mess with swifties. But she started receiving death threats because she was fighting with teenagers in the comments on tiktok because she thinks BTS sucks. She called someone a brain rotted parasite who doesn't know what good music is. When she showed me the death threats I said "Why are you arguing with kids online?" She was upset that I said that and said I'm her husband and I need to do something. What exactly? I wasn't gonna go argue with teenagers on tiktok for her. I told her to just block people and don't piss off BTS fans anymore. There's nothing we can really do about this. So now she's mad. I'm not really sure what she wanted me to do is the thing.
