You habe to read it while laying in your back

Mostly people who get called nazis are saying fascist stuff. So while the term nazi isn't correct it is meant as an insult to their ideolegy by drawing a line to past fascists.

Just my personal opinion based in how they report on different topics compared to other German news outlets. They often have a very nationalistic view on topics compared to other German news. They also often use populist headlines. Not as often as BILD but compared to reputable sources like tagesschau it is very obvious. It's notable that they want to put a pro german spin on stories.

Keep in mind that DW is the german propaganda paper.
