My husband and I are both in our first marriage and have been married for decades. The recent SCOTUS ruling will not affect us personally in any way.
But what I do strongly believe is that the assault on the traditional family as an important and valuable American institution has been further eroded and made unimportant and irrelavent. By SCOTUS now, illegally and way outside its constitutional authority, forcing us to change the definition of marriage and thereby make marriage into something it never was and was never intended to be, more and more young people won't bother with it. We will have ever more children born out of wedlock and be much more likely to grow up without the advantage of the traditional family with a loving mother and father in the home.
Marriage has always been about the children that were assumed to be the logical result of the marriage, and all marriage laws in all 50 states were designed first and foremost to protect the children. You cannot change the definition of something, however, without making that something into something different than what it was.
IMO, while I have always supported the necessity and ability of gay people to have the necessary protections and rights enjoyed by others, and I have no animosity whatsoever to any gay person, the SCOTUS decision has done irreparable damage to the institution of marriage and we as a people, both straight and gay, will be the worse off for it.
