Its sad to see that muslim parents dont want their kids marrying other ethnicities outside of their own which goes against the teachings of the prophet SAW.

O people, verily your Lord is One and your father is one. Verily there is no superiority of an Arab over a non-Arab or of a non-Arab over an Arab, or of a red man over a black man, or of a black man over a red man, except in terms of taqwa.

(Classed as saheeh by al-Albaani in as-Saheehah (6/199)

This was the final sermon delicered by the prophet SAW if that does not strike its importance then idk what will.

Another Hadith :
Abu Huraira reported: The Prophet, peace and blessings be upon him, said, “Verily, Allah has removed from you the pride of the time of ignorance with its boasting of ancestors. Verily, one is only a righteous believer or a miserable sinner.

All of the people are the children of Adam, and Adam was created from dust.”
