Not to speculate too much but according to court records, Beate Zschäpe browsed Greenpeace news before setting the camper ablaze.
Where the fuck did you get that nonsense?
The German far-right has never been anti-environmentalist as such, much to the contrary: On the first Green party convention there were a lot of people who were of the opinion that not enough is being done for the German forest. Until they got kicked out with prejudice. It's the centre-right which likes to bury nuclear waste in leaky barrels in leaky salt mines.
This is also bullshit. The AfD literally does not believe in climate change and wants to get the coal industry running again. The Greens are pretty much the number 1 enemy of the far right in Germany and everyone caring for the environment is seen as a menace, because the whole topic kinda became a left leaning political topic somehow (likely due to US politics).
