Listen, I really didn’t understand what you were saying in the first place, so no need to get personal. Also, you seem to misunderstand what I wrote. Let me re-iterate: in this case, it’s even unlikely that there is a case which would end in court, and of so, I bet the court would rule in favour of the artist. But there are good reasons that showing off racial insults (and Nazi symbols, since you brought up Nazis on stage) is illegal under current German law. The law is far from absurd, and also doesn’t get absurd in said case.
It might be that I simply misunderstood your phrasing. But then again, your last line seems to implicate that you think that racial slurs should be covered under freedom of opinion, or expression. That’s bullshit.
The thin veil here is the veil of civilisation under which barbarism stares into our face. It never goes away, but we might as well try not feed out and celebrate it under a different name.
