CRR-
This ad hominem mocking the developmentally disabled courtesey of a liberal...
The only person I was mocking was Sarah Palin. Are you calling her developmentally disabled? If so, we agree! Still... I don't think it counts as an ad hominem because I wasn't making an argument, I was making a statement (and I was being satirical like Rush Limbaugh).
So what does Sarah Palin have in common with a genocidal group of populist socialists?
Ask Seth McFarland. I didn't write the episode. I just found it funny because I don't like Nazi's and I don't like Palin, in general. Therefore linking them together made me laugh.
