I have been using TheStorygraph and I am amazed by the quality of some of the recommendations.
Could you invite me? The open registration seems to be closed by now.
You're right, but being afraid of radicalization is not the same as being xenophobic/racist. The fact that this guy supported the AfD is a key piece of information in my opinion.
Since the article does not mention it at all, the person in question was following and sharing racist rhetoric online - posts from AfD and Elon Musk, for example. He feared an "Islamization" of Germany and seemed to be very angry about it.
It is an important observation to report on, especially because people would assume him to be a racial stereotype that he is not. It is also responsible to include the details given that so much about him has already been shared online.
