::Basically, I'd agree with "because it would supposedly result in improvement of the gene pool" when talking about specific eugenic policies. That would make sense. Interracial marriage was banned in the US because supposedly it degraded the gene pool. Same for other policies. But this page is about eugenics, and those policies should only be considered from the point of view of eugenics. That kind of stuff would fit much better on the coercive sterlization page, for example. Or miscgenation, etc. Among the various reasons why such policies have been enforced  eugenics. 

 ::But on the eugenics article itself, it just doesn't make sense.
