>"After a few minutes they realize that the glass in front of the painting is not that expensive and all is well. Or is it? That's when they have time to think about destruction and maybe what these people just said about climate change."

I don't think this is true, for most people. People do not generally stop and think in a deep and reflective way after getting angry about something. What these activists did was not inspiring and it did not look like justice. They aren't Rosa Parks 2.0, they're people throwing liquid at inanimate objects (which people beautiful and valuable) and gluing themselves to objects at a museum. There is no powerful symbolism of defiance here, this is not speaking truth to power. They just look like childish weirdos. Childish weirdos do not make me self-reflect and question if I'm actually the one doing something wrong.
