I think she was wrong to do what she did, and she was not able to formulate a coherent sentence, only mock the guy. He may be mistaken to support Israeli-style national health care, but he was giving a sincere opinion, and there was no reason to attack him like that. To yell nazi slogans at a Jew, just like he says, is a shame. Probably she's not a nazi, just rather slow. If he was an Obama-lover or calling for land giveaway to Fakestinians, maybe such a thing is more justified but even then it's probably inappropriate to yell that phrase at a Jew like that. And this was nothing like that. He's just talking about healthcare.
They both seem ignorant, but I sympathize with the guy for being attacked like that.
