Disagree: most halfies I know are stunning! Although I see your point about it not being good because of race issues between the two families.
Have you read Mein Kampf recently? It's all about mixing races and the consequences...
I'm properly british and I find quite a few african/white mixed people or Mediterrannean kind of people attractive. Plus By mixing your race's genes you produce healthier children.
Mate - I love being mixed race - and daymn - some of the hottest people I know are your mix!
You get unattractive people who aren't mixed-race too you know.
You might have had a reasonable argument going along the clash of cultures side etc - but not the looks - most people would love a mixed race bf/gf
It is only an issue if the parents are very traditional (racist), and dissaprove. In Britain at the very least, that is becoming far less common.
Relationship does not necessarly = children.
