I think it’s about this song: https://www.youtube.com/watch?v=FXGoN6xBeD0
I have no knowledge about songs being banned in the US or not, but I disagree with your assessment of laws being a waste of time. I’m not if favor of a police state whatsoever, but I would consider attending concerts of some right-wing rock bands as a first step towards radicalization.
Hence, preventing those from occurring where possible might keep gullible people out of the influence of radicals, or in the worst case, help keeping tabs on potential future offenders by being able to charge them with something.
Yeah, I mean, I agree on principle sure. If I was running the music festival I would probably take that attitude sure. The issue with when it becomes the law, is that it’s never going to be you or me deciding what might be the first step towards radicalization and what needs to be kept away lest it influence people; it’ll always be people who think the Palestine protest songs or Rage Against the Machine are the first step towards radicalization that we really need to be looking out for. So better not to give them the power to shut down the music they think is dangerous.
