The context is an article in which Romney (according to the Huffington Post) made a statement that argued the Palestinians' economic woes are because of an inferior "culture", compared to Israel. This article obviously generated tons of comments, including this one, by a Huffington Post blogger:
Beyond the fact that this statement is blatantly a lie (I don't think many Israeli Arabs would consider the Palestinians to not be human), it is simple bigotry towards Israelis. Such a statement would be bad enough from a commenter, from a blogger is simply outrageous.
The best link I could find at the Contact Us page is the general email address firstname.lastname@example.org. I recommend all of us email them with a complaints about this bigot and there's a slim chance they might do something about it.
