If the birthrate among a race is high enough, a small amount of intermarriage should be able to be bread out. EG with each passing generation, someone who is half foreign race becomes a quarter, then an eighth, then a sixteenth and eventually they're basically indistinguishable again. What I'm wondering is for a given birth rate, how much interracial breeding can a race absorb and still basically remain itself. I don't think the answer is zero, but I'm sure it's not very high. On the other hand, interracial marriage I don't think is high enough to threaten the existence of the main classic racial groups, even with low birthrates.
Based on my arguments, you can accept mixed race people as individuals but as a group you don't want the main groups to go extinct.
