I'd think that seriously advocating book burning at any time would disqualify you, since presumably there are equally qualified candidates for the UN's cultural heritage agency who've never advocated destroying cultural heritage. But Israeli society is toxic anyway - especially compared to the glory that is the contemporary Egyptian public sphere - so no loss:

Egyptian Culture Minister Farouk Hosni, a candidate for the top job at the United Nations culture agency UNESCO, apologised on Wednesday for calling for Israeli books to be burnt... Hosni said he regretted his words, adding that they had allowed detractors to associate him with things that he found hateful. "Nothing is more distant to me than racism, the negation of others or the desire to hurt Jewish culture or any other culture," he wrote. Philosopher Bernard-Henri Levy, film director Claude Lanzmann and Nobel Peace Price laureate Elie Wiesel last week quoted Hosni as saying he would burn Israeli books and calling Israeli culture "inhuman". "Let's burn these books; if there are any, I will burn them myself before you," they quoted Hosni as telling a member of parliament who had confronted him about the presence of Israeli books in Egyptian libraries last May.

He also banned Israeli books and films from Egypt's international book and film festivals. Plus he's stated that Jewish culture exists only to the extent that it steals from other cultures. So what could be more natural than letting him decide if Israeli and Jewish heritage is important?

Anyway, he's almost certain to get the appointment. Of course he is.
