It's not the first time the Supreme Court has had to intervene on the behalf of couples who are in love to grant them the right to get married.
Back in 1967 the Supreme Court struck down all laws that forbid "interracial marriage". That's less than 50 years ago!
Some people still have issues with that as well. I'll never understand this need to deny any group of people rights based upon who they are. Historically in America just about every group has had to fight and protest to get equal rights whether it's been women, minorities, and the LGBT community. There's always seems to be a price to pay.
Logically it makes no sense. Whether a gay couple is living together or married it doesn't change (my choices) at all or my life in anyway.
Some people use religion as their excuse. However upon close examination you will find that most if not all believers "cherry pick" which scriptures they will follow.
"Whoever does any work on the sabbath should be put to death."
"Anyone who curses their father or mother is to be put to death."
You don't see many believers pushing to enforce these scriptures.
And clearly very few people observe the "love thy neighbor as thyself" and "judge not lest ye be judged."
Hate is usually attached to fear in some way. Some people may believe that being gay is a choice and therefore they see the legalization of marriage as vehicle that will increase the number of gay and lesbian relationships. Others say they worry about "confusing" children which may cause them to become gay. The irony is all gay people had heterosexual parents!
Gays and lesbians make up less than 5% of the world's population. Same sex marriage is not "mandatory". No one has to marry someone of the same sex. Therefore each person gets to marry the person they love.
In the big picture of things holding down a job, taking care of one's own household, staying healthy, and planning for retirement are enough to most people busy without worrying about whether two women or men have the same rights to get married as I do.
50 years from now I imagine future generations will wonder why there was so much resistance to treating gay couples equally to heterosexual couples.
