No, quoting an example of Volksverhetzung is not illegal, if you're not actually attempting to incite hatred.
I can give you a counter-example (although in France where we have similar laws). Patrick Sebastien, who is a well-known French humorist has been convicted for exactly that (he impersonated Jean-Marie Le Pen, far right politician, in a satire song "casser du noir").
Sorry but I can only find a reference to a French article http://www.liberation.fr/medias/1996/03/13/patrick-sebastien...
The judges concluded that this was indeed an incitation to racial hatred, which is illegal in France.
What you seem to be taking about is the new one, which breaks many things in the hopeless attempt to maximise enforcement of the original laws. This is a recurring theme in lawmaking: everything has a certain maximum level of reasonable enforceability, and when laws are written to increase enforcement beyond that limit they universally turn out bad.
Do you know how strict those laws are? I mean, you just said that, albeit in a quotation, so I imagine that at least is out of the scope of the law? Or would it be something that got you in trouble if someone reported it?
