It's a really big deal at this time of year for people to believe in something. Ask anyone.
For example: certain hard-core, anti-gay, types believe that I am going to hell. Furthermore, they believe that *I* should believe I'm going to hell, too. You see, it's not enough for them to believe it. It's absolutely essential that everyone else believe it, too. Especially me. And people like me. People who don't believe what they believe. People like me who believe that there is a God, but it's not their God. People like me who believe that God doesn't make garbage, and doesn't make mistakes, and doesn't dream up various "gifts" for human beings to spend a lifetime "trying to overcome."
I believe that people are free to believe pretty much whatever they want to believe. From a guy who floats around on a cloud all day, surrounded by Seraphim and Cherubim, to the Tooth Fairy and Santa Claus.
I also believe that I am under no obligation whatsoever to share in anyone elses sun-drenched, half-baked, crackpot beliefs. And nobody is under any obligation to believe in mine.
But I am entitled, despite anyone's beliefs, no matter how "core" those beliefs might seem to them, to share, on a fully equitable basis, in the contractural life of America -- and that includes the ability to contract with another individual for our mutual love and protection, i.e. "marriage."
There is no wiggle-room in there for anything else. Especially belief.
Merry Whatever It Is That You Believe!
