In the future will there be no truly white people?

Given the increase in bi-racial children being born each year, will we eventually reach a point (accepting this will be many centuries, perhaps even millennia from now) where there are no white skinned people with natural blonde hair and blue eyes?

This is based on the (incorrect?) assumption that the “dark” (i.e. Asian, Oriental, Black etc.) gene is stronger and that bi-racial children are more likely to have dark skin, brown eyes and black hair.

And is there anything wrong with an individual wanting to preserve the white/caucasian race, while still supporting equal rights of all races (just not where it concerns bi-racial reproduction)?
