I’m from South Appalachia, so grandparents, aunts, uncles, cousins are still part of nuclear family to me. Nuclear family remains the most effective form of government, and the most stable and safest environment for raising children. This is more than a social construct, it transcends societies and has numerous natural benefits. This does not mean that such arrangements are the only way to effectively raise children or families, but any efforts to disrupt the nuclear family or curtail the natural benefits are unnatural and pure evil.
