>>9765320It happens a lot here but we have a black population of leas than 5% so if we mixed with all of them spread them out evenly across the british isles and continued to do so with the half-breeds and quarter-breeds etc it would have no significant affect on the population as a whole.
If americans did this it would be a different story especially when you add their latino population.
We have a pretty sizeable south asian population though of about 10% if im not mistaken, i wonder if mixing with them also would have any lasting affect
