Well, it's wildly popular elsewhere in the Mideast and the Islamic world... so why not in Turkey too? Blogger Homocon notes that:
"Booksellers in Turkey are reporting soaring sales figures for "Mein Kampf," or "Kavgam" in Turkish. Hitler's political manifesto has been a top 10 bestseller in the past two months...and at least two new Turkish language versions of "Mein Kampf" are now out in paperback.
Asked to comment on the phenomenon, government spokesman Cemil Cicek said: "There is no racism in this country." Homocon has more about Turkey's new bestseller.
A while ago, Winds of Change noted the popularity of Hitler's Mein Kampf in the Arab world. National Review did a whole article on the subject, and "Their Kampf - Hitler's book in Arab hands" is excellent. This isn't a fringe phenomenon, either... as MEMRI's translations often remind us it's a mainstream thing in government newspapers. Ahmad Ragab, a columnist for the Egyptian government paper Al-Akhbar, is only one example among many opinion-makers to "give thanks to Hitler, of blessed memory," and whose only expressed regret is that Hitler had not murdered every last Jew. There are many other examples.
A while back, a blogger observed that the great question of our time is whether the Arab/Islamic world can reconcile with tolerance and modernity - and noted that nobody knows the answer. Still true, on both counts.
UPDATE: A small glimmer of light. After getting a lot of press attention in Europe, Turkey banned the second printing of the Turkish translation.
