I don't know that I buy the media explanation that he was a far-right supporter who backed Musk. Makes no sense. What does make sense to me is him being a traditional jihadist making a strike at the "unbelievers" on the day they celebrate the birth of their Savior (which is odd in itself since he was born during the harvest season and not in the dead of winter, plenty of evidence for this BTW.)
I spent 5 months living in Germany near Stuttgart and spoke to many refugees and ethnic Germans. As a patriotic American who wore his US flag t-shirts as often as possible (I took 4 of them), I was constantly being asked about the US and was only too happy to oblige.
The odd thing was that with the exception of one female Turkish cab driver and the staff of a Turkish restaurant, every single refugee that I spoke to criticized the west during the 5 months I lived there.
I'll never forget the Afghan man who approached me at a bus stop. He'd traveled a long way to reach 'The Promised Land' of Germany, but he couldn't stop complaining about it. He thought western women should be covered when they went out, that there was "too much" freedom in Europe etc. etc.
I always pushed back with these people, reminding them that thanks to the German people, they now had full bellies, money in their pockets, a roof over their head, and finally peace. But it was to no avail.
It seems like they want western countries to be a carbon copy of the countries that they fled from. Which begs the question why did they bother leaving in the first place? So no, I think our Christmas Marker murderer was exactly what he seemed to be. Someone looking to strike out at the evil west in order to earn his place in Paradise, only to wake up to a Hellish afterlife.
I have just got to say that you are writing down many of my thoughts exactly, and you kind of explain in a way I have a hard time writing down myself, but it seems to be very true in so many ways.
