I hate these ecofascists. Funded by big oil, they go around vandalizing and causing trouble for working class people while claiming to be "fighting climate change". Compare that to serious people, like the Houthi: deep unserious people.
The poster doesn't even express concern for the standing stones, just muh optics posting as usual.
I like Stonehenge. I know some people find it unimpressive, but I think it's cool as fuck. I think it's an appropriate target for protest against a failing apocalyptic system, may its scars record the protestors' struggle forever.
I don't think vandalizing an archaeological site is going to suddenly change Big Oil's mind. If you want to take down Big Oil, direct action against it is a good place to start.
