The more to mix, the better the gene. Inbreeding cause retardation, out breeding create smarter gene to counter defects and virus, also eradicate genetic disorder if not mistaken.

Blood don't represent any uniqueness except genetic disorder, no super gene ever identified, tradition and culture is a practice not inherit, your words are all revolved in Christianity and got mixed up in your mind.

Is that the only way to preserve religion? I think there is a tendency of getting out of Christianity or other religion except Islam, my friend marry a Christian and only become a believer after 10 years, i am sure you'd welcome that but the other way around is your worried. Buddhist never need to prioritize religion in a marriage because there is no power to gain and are not at war with other religion.
