Quite non-sense this.
There are hundreds of millions of Turks, Iranians, Indonesians with Islamic names (mostly Arabian origin).
There are hundreds of millions of Europeans, South Americans with Christian names (originated in the Middle East).
There are hundreds of millions of Hindus with names which were never native to Indus Civilization.
And on the opposite side, there are millions of Pakistanis with the local names.
What point are you trying to make? If a white European converts to Islam and changes his name from Cat Stevens to Yousuf Islam, does that mean he is no more a European?
