Why should 'considering self' be the sole argument?

Omer-pasa Latas didn't consider himself anyway, thats not the age of nationalism, he was an Orthodox Serb, who under devsirm became a Muslim, just like Bosnian Serb Mehmed-pasa Sokolovic, no reason to remove him.
Josif Pančić converted to Serbian Orthodoxy when he came to Belgrade and assimilated, I'm not going to go into his personal family origins not realy nown.
OK, will look further.
How can it be "hardly doubtful"? You seem to be more sort of opposing the addition of any Serb-Catholic. Please do not remove Fabris.
