The letter Q was illegal in Turkey from 1928 until last month

Are you kidding me? "Muhammad" was never illegal in Turkey. Show evidence of prohibited.

Turkuaz.

Have some Häagen-Dazs if you really think using "the wrong letters" is illegal in the US.

The legislation you gave shows Turkish alphabet and Q, W, X is not included in this alphabet. AFAIK, generally country laws only accepts people/company names in their alphabet.

Think that legislation like USA's alphabet. They didn't have Ğ, Ş, İ etc. in their alphabet so people/company names doesn't have these letters. Is that means Ğ, Ş, İ is forbidden? News like this for dramatize the status of kurds in Turkey :)

To put things in perspective, you really need to take a look at the past to appreciate modern Turkey. The Ottoman empire was ruled by Sultan's who wielded absolute power, much like the leaders of other Arab nations today. Prior to the Sultan's were the emperor's of the Holy Roman empire, who wielded power so absolute that even medieval Europeans would have found it unsettling. Much of the symbolism used by European royalty was copied wholesale from Constantinople in attempts to achieve a similar measure of control.

Ottoman society, like many Arab societies today, was heavily inclined towards absolute rule by "strong men". Where most of Europe gradually weaned itself off of absolute rulers by gradually limiting or subverting the power of monarchs over several generations, Turkey literally went from absolute rule to democracy in a single generation. Kemal was an officer during the first world war, which Turkey was on the wrong side of and wound up being partitioned by the allied forces. He played a huge role in reunifying Turkey through armed conflict that expelled the occupying forces. The last Ottoman Sultan was opposed to Kemal and called for his death, but the unification forces instead abolished the sultanate and declared a democracy. Kemal was held in such esteem that he was easily elected to lead this new democracy.

Here's where things get interesting... Kemal's revolution and declaration of democracy are hardly novel. Many nations have undergone similar transformations, and many of the newly elected leaders soon turn into despots. Cultures that favor "strong men" tend to encourage this. Kemal introduced reforms intended to westernize Turkey. Western dress, even hats, were heavily encouraged while his "Hat Law" banned turban's and fezzes (No, the doctor would not have been a fan of Ataturk!).

The new alphabet, seen in light of this wave of westernization, is particularly interesting. Ankara, Istanbul, and many other Turkish cities are full of monuments covered in arabic scrip proclaiming the awesomeness of various Sultan's. It's not unlike how Washington D.C.'s Lincoln memorial, etc., glorify the U.S. system of government, only the Ottoman empire had been accumulating such monuments for a lot longer. The Sultan's of the Ottoman empire lived in the shadow of Constantinople's emperors, so they tended to play themselves up rather a lot.

If you tour Turkey today, your university educated tour guides (practically every guide in Turkey has a degree or two) are extremely unlikely to be able to read a word of arabic script. The new alphabet effectively severed Turkish citizens from centuries of extremely high quality propaganda that the Ottoman empire had accumulated to support the sultanate's rule.

Kemal's legacy is not without it's dark spots, but the "strong man" culture of the Ottoman empire has largely abated. Obviously, it takes time, as people change slowly. Turkish citizens today are more likely to revere Kemal himself as they would a Sultan rather than their prime minister or president. The military has historically seen itself as the guardian of Ataturk's legacy, which has led to some truly unusual coups that, bizarrely enough, have probably kept Turkey on the course of democracy, although recently the power of the military has been gutted.

The Turkish alphabet might be interpreted by some as a form of oppression, but it's adoption was more about breaking with the past and embracing democracy and the west. Compared to it's Arab neighbors, Turkey is astoundingly western and unusually democratic.
