Lol at this top comment on my post
This retard brought up fucking dog breeds. By that same token are pugs crossed with english bulldogs "better" and healthier than purebred german shepherds? Are chihuahuas crossed with pugs smarter and more trainable than a purebred border collie? 250 updoots for this idiot's dumb argument totally misunderstanding what "hybrid vigor" even means!
Quoted pop sciences means I want to fuck my cousins:
A study of Icelanders sheds light on how relatedness affects reproduction.

Chief takeaway here is that at third cousin the genetic distance is great enough mitigate any inbreeding depression and in fact such a coupling produces the most fertile offspring. So as the USA has at least 100 million white people that's definitely more than enough of a gene pool to not have to worry about inbreeding depression, therefore what the cuck OP said is retarded.
