How do you think the other races got here genius? Race mixing has been going on since the beginning and will not stop until the end. People need to learn to live with it whatever the combo and BTW, you talk as if pure race kids (what ever the race) are good looking...They're not. Most people are average no matter what the combo. This isn't the 50's the children of these unions aren't marginalized. For fucks sake mate we have a mixed President.
And yes, the human race benefits from diversity. So race mixing is good genetically.
Usually when black and other races mix, the black gene dominates. It's that potent.
I don't think new races will emerge out of interracial mating, it's just going to be a minority group in society that look odd due to their sexual lifestyle.
Plus, i don't understand modern society and it's disregard for nationalism and ethnic heritage. You must mate with your kind or very close to it to maintain that lineage.
...but i understand why black fellas go for other races, i mean, it's pretty much self explanatory.
