Sacred Haven of Debauchery

It's a stretch because it only works in exceptional cases of complete ignorance and rejection of additional reproduction options, and where's the excitement then? And as for the descendants of these cavemen – there's nothing remarkable about them, whether it's one, a thousand, or even a billion more or less – it makes no difference. And of course, we shouldn't be retarded romantics and think that we have seven billion lineages from seven billion cavemen. We have seven billion lineages from a few tens of thousands of original cavemen, so subtracting the genes of a single cuckold is not even a statistical error, but just a speck of dirt on the sole of the overall genealogy. In short, guys – don't be sad, it's not that bad.
