Interracial relationships are not wrong, but it does come with its own set of challenges. I am personally against interracial relationships for the sole fact that it causes confusion among the children and future generations.
Children become confused about where they belong, in which racial group specifically. In future generations, the interracial relationship which created the grandchildren can surface again. For instance, if your grandparents were an interracial couple, you may be black, and have relations with a black person, but your child may come out very light skinned because of this previous interracial relationship.
This may not seem significant, but as a child, being able to belong or identify with someone or a group of people is crucial.
You also have the obvious issues with regard to the religions and traditions of a partner from another culture.
