I didn't say a word about race. I simply said that there were no Turks in the area until the 13th century. Nicholas was all 4th century, as you point out. I'm very familiar with Santa, as it happens, and still a believer in the REAL Santa.
It wasn't until the 1200s that the Uyghurs beat back the Byzantines from the area, but weakened themselves, got assistance from the Seljuks. It's the Uyghurs and Seljuks together that make Turkyie Turkish.
