The point, he is from same tribe of Quraysh. You are trying to separate that identity from him. Ahal AlBayt is a linage, not a tribe. So you need to stop referring to him as from Ahal AlBayt as if that is the tribe he was born out of. He is a Qurayshi, and so are the rest of the guys that were related to him too. Prophet Muhammed was an unusual man, he is very straightforward and mysterious. He is someone that cherishes God and has no itch for anything in this life. So yes he criticize his own people, and if he was alive longer, would criticize Iranians, Turks, Asians, or anyone else for that matter. He is very unlike ordinary people in his personality, and he won't get along with people. Back then he didn't either, he had to teach Islam however. So you're making misleading people by implying he is loyal to a clan, linage, ethnicity, or nationality. When he is someone that God made alone and different than everyone else, for reasons only God knows.
I don't know what you mean by Ahal AlBayt is holy either. No one in Ahal Al Bayt is getting preferriantal treatment to those who aren't. They don't have special powers or exaggerated qualities like some try to infer.
