The extra nail in the coffin is that he didn’t apologize or show concern at all. He deflected with a bullshit comment about it being a roman salute even though that’s nonsense. Any sensible person in his shoes would have immediately said fuck nazis, that was dumb, I fucked up, not what I meant etc.
Then he goes and speaks at an AfD rally and says germany should move on from its embarrassing past or some nonsense. So if there weren’t already 5 nails in the coffin, he just filled it with c4 and blew it up.
He does great work!
