I would love to be able to draw that parallel but the climate guys haven't gathered in the thousands to storm the Bundestag yet.
Climate activists destroying paintings, making micro or macro aggression will annoy people more than focus on the problem of climate. I think most of the people already know about climate problem. Destroying painting will not make people go out from their homes and protest.
Don't get me wrong, radical green activism saddens me. I think the vandals that recently damaged the Brandenburg Gate should not be able to avail of any get out of jail free passes, and existing laws should be strengthened to discourage eco-vandalism to the fullest. I just can't put this sort of activism and J6 side by side and say they are the same thing.
