Nurture not nature!
Oh, and unrealistic, idealising nurture due to unwillingness to look at nature. That nurtures problems, we do not deal with rational, instead we accumulate problems and shift the blame, until the buildup throws society on the side.
Oh, and if invisible nature, we pretend to nurture, then blame the failings on the individual.
Yes, im fun at parties.
Also the conclusion is that the rate of unrelated children is remarkably low not high.
