You are right that Islamophobia is quite common in Germany. And when you put „left wing“ in quotes you seem to acknowledge that there are different understandings of left in Germany as there are in other countries. And it depends on which one you look at, how much of a problem that is in the specific group. BILD being the best selling „newspaper“ mostly depends on two things: a) it’s one of the few publications sold nationwide. b) It’s not really a newspaper. It is and always has been a right wing outlet spewing bigotry, hatred and misinformation. And that is something that sadly sells well throughout all the remaining liberal democracies. And it’s festering in Germany as well, our local right wing extremists currently reaching close to 30% in polls. But that still leaves 70% who are not fully gone yet. And I hope you‘ll meet more of them in the future.
