I wouldn't worry about human genetic diversity.
What is true, is that mating between closely related individuals (say
brother and sister) will have a higher chance to produce offspring
homozygous for larger number of genes, than mating between not-so-closely
related individuals. An allele can be lethal in homozygous state, while
the same allele could be fine if heterozygous, as long as the other allele
is ok. 
Inbreeding does decrease genetic diversity, increasing homozygosity. 

Nach.
