There hasn’t really been many instance of art getting destroyed. This is legitimate imo, it gets in the news and no real damage is done. Personally, I think it’s not far enough.
If oil companies get their way, whole countries are going to be destroyed, not just paintings.
It’s also plain to see that any form of protest against oil companies is quickly villainized by the media. There’s an agenda at play when you can’t march, stand in traffic or just throw soup at glass.
