Let's talk about a legitimate family structure. The nuclear family of the 1950s, 2.7 children, a stay at home Mom and a breadwinner Dad is all but obsolete.
The human race as we know it, has been around about 100,000 years. Certain behaviors and attributes have developed over time. In relationship to offspring, about 3 models have arisen and endured. The first is the nuclear family. This is found on every continent on Earth. This is the most civilized and stable of the models and encourages a stable society. Counter culture appears to have the attention span of a goldfish, though the reality is that the counter culture is a deliberately destructive force. Civilization learned long ago that a society functions best if the males are enticed into the rearing of children. The family unit encourages the male to engage in the family unit by linking sex with family structure.
The second model is the tribal model, an alpha dominates and creates a harem of females. Strife is inherent as lesser males compete for females.
The final model is unstructured, animalistic encounters, generally found in failing and crumbling societies, such as ours. Always a short lived situation.
Blended families of divorced parents, single Moms, or Dads, an elderly relative living in the home with their children and a committed homosexual couple all make up families.
All are signs of a destabilized society.
Do you think the state should be the arbiter of what makes a family and what does not? Gone is the Conservative mantra that government should not interfere in your personal life if you believe that one family is 'legitimate' while another is not.
Who said anything about the state?
Let me ask you, do you think Water Polo should include golf?
And again, for the umpteenth time, siblings already enjoy a next of kin relationship. The next of kin relationship is established by the marriage contract. Why would siblings require a seciondary next of kin relationship?
WTF are you talking about?
