Es decir:

una persona del medio oriente, suscriptor de un partido nazi, decide matar personas probablemente mientras piensa en cómo eso va a vencer a los globalistas de izquierda y acaba con esos "terroristas musulmanes" que estan islamizando a evropa

Rightist and fascist, it appears.

the thing is that in Germany most media isn't even having this connection between the terrorist and the AfD in their focus. Also the public debate isn't covering this enough IMO. There is way to much focus on his nationality, which is completely irrelevant.
If the supporters of the AfD get told that the terrorist sympathized with the AfD they call it fake news because it would break their narrative. There is a lot of hatred going on in this debate, coming from the far right pushing against minorities unfortunately.
