The Wikipedia edit war on hummus has been raged for various reasons for years -- and simultaneously mocked by onlookers and even participants. It became so controversial, the article is categorized under The Arab-Israeli Conflict and subject to the rule that only one revert can occur in a 24-hour period.
The primary controversy has been whether hummus was first Israeli or Arab. The current terminology is "Middle Eastern" -- no one can disagree about that. People were especially offended by using the term "Palestine" in discussing its origins. In my studies, Palestine is a perfectly legitimate geographic area term, but it has been so politicized, it can no longer go uncensored... and then it drags hummus down with it.
