yes, but this applies to sane societies. in current societies none of the cons of rape you mention exist. std's are largely treatable, inbreeding - why? you know to avoid raping a relative , most males are physically stronger, females don't have mates but just men who empty themselves in them and leave, trauma of a beating might, rape itself hardly, modern medicine will look out for you, a single parent household is normal now, mates can't kill rape ape children for it is illegal, there are no such clans today, at least they don't have the power they had before.
