You want to know who the turks are? The turks are the new owner of Anatolia, from Edirne til Ardahan since 1075 after the turkish troops of the legend army comander Alpaslan defeated the troops of the Byzanz Empire. Of course the turks are mixed with the native population of Anatolia.
But this not so important for the future as long as they're not mixed with the African population. One Kazim Kazim is enough, we don't need more
All at all turks are human beeing like the others. Not less and not more! There are also goods and bads between them
