Restricting marriage as its been done for THOUSANDS of years is in the compelling interest.
how so?
By assuring that children get the best start in life possible by having both a mother and a father: the reason marriage was created; to remedy all the inferior situations of children having both a mother and a father. Obergefell just substituted an inferior situation for the cure for that inferior situation. And they did so without permission or representation of children, or even the collective states' interest in how children grow up...without both a mother and father...
PRINCE'S TRUST 2010 YOUTH INDEX SURVEY or with both a mother and father:
(Below: a study with 3,000 surveyed young adults who grew up both in normal mother/father homes and those raised in lesbian homes. It was done to contrast small-sampled and cherry-picked "exemplary outcome" lesbian homes submitted "as science" by other sources. It showed, in agreement with the Prince's Trust findings (first link here), that children fare better in homes with both a mother and father compared to two lesbians....well...duh..)
The New Family Structures Study (NFSS) is a
social-science data-collection project that fielded a survey to a large, random sample of American young adults (ages 18–39) who were raised in different types of family arrangements. In this debut article of the NFSS, I compare how the young-adult children of a parent who has had a same-sex romantic relationship fare on 40 different social, emotional, and relational outcome variables when compared with six other family-of-origin types.
The results reveal numerous, consistent differences, especially between the children of women who have had a lesbian relationship and those with still-married (heterosexual) biological parents. The results are typically
robust in multivariate contexts as well, suggesting far greater diversity in lesbian-parent household experiences than convenience-sample studies of lesbian families have revealed. The NFSS proves to be an illuminating, versatile dataset that can assist family scholars in understanding the long reach of family structure and transitions.
How different are the adult children of parents who have same-sex relationships? Findings from the New Family Structures Study
Children raised in inferior homes turn out to be statistically a burden upon the criminal justice system and mental health services. They are also more depressed, unhappy and even suicidal. So, states have an extreme vested interest in who they subsidize with tax breaks "as married" vs those they do not entice with money to play house around children.
