I don't like her deliberately offensive MO. I am surprised anyone here is actually debating the idea of Jews owning German cars as I think it is just a vehicle (enjoy the pun) for her to say a whole bunch of "offensive" things.
I am sure one day in the future, a female comic will come out on stage naked and say "fuck faggot slut bitch cock nigger jews cunt piss incest hahaholocuast", then stick a vibrator in her vagina and defecate on the front row. The audience will erupt with guffaws. The comic will take a bow and say "thank you, Sarah Silverman; you were a trailblazer"
I'm okay with "offensive" as long as it's funny. She's not funny. :(
