I like that comparison, he is kind of the troll of philosophical history. The interesting thing about Nietzsche, though (esepecially in
Geneaology) is that he takes on so many different voices to address different existing philosophies such that you can't really say (although many have) that he's
anti-semitic (In fact, IIRC he seemed to dig the old testament Jews' style) or
anti-christianity.
The difference between his adolescent jabs at Christianity, Judaism, the English, etc. and an ironic motivational poster is that he had a sort of overarching point to make. Among other things, he wanted to demonstrate that existing philosophy was essentially a really deep catalog of the personal biases of a bunch of well-spoken white dudes.
