Is there anything wrong with interracial relationships?
No, I’ve been in one for 30 years, three kids and two dogs.
Why are people against it?
Centuries of ingrained institutionalized racism.
What are reasons it’s okay, and what are reasons it isn’t?
Like most other relationships, it’s ok when both parties feel that the sum of the parts is better than the whole; when there’s the emotion called “love’ involved; when there are common feelings and goals.
It’s not OK when either party thinks the challenges of the interracial aspect of the relationship outweigh any or all other reasons for the relationship.
