I have been to this point unwilling to sign on to same-sex marriage primarily because of my understandings of the traditional definitions of marriage. But I also think you're right that attitudes evolve, including mine.
If we are to keep our flock at the highest pitch of excellence, there should be as many unions of the best of both sexes, and as few of the inferior as possible, and that only the offspring of the better unions should be kept.
God bids you not to commit lechery, that is, not to have sex with any woman except your wife. You ask of her that she should not have sex with anyone except you -- yet you are not willing to observe the same restraint in return.
The changes in thinking about same-sex marriage have come slowly at first and then in rapid course. If such change is possible in this area, is it also possible in the vexed and sordid realm of race relations?
The goitre of egotism is so frequent among notable persons, that we must infer some strong necessity in nature which it subserves;such as we see in the sexual attraction.
In spite of conflicting signals - and in spite of a popular culture that sometimes puts down their innocence - most of our kids are good kids. Large numbers do volunteer work. Nearly all believe in God, and most practice their faith. Teen pregnancy and violence are actually going down. Across America, under a program called True Love Waits, nearly a million teens have pledged themselves to abstain from sex until marriage.
There is a brief time for sex, and a long time when sex is out of place. But when it is out of place as an activity there still should be the large and quiet space in the consciousness where it lives quiescent. Old people can have a lovely quiescent sort of sex, like apples, leaving the young quite free for their sort.
We're all animals, that we all respond to the same stimuli. If you want to motivate somebody not to have premarital sex, or motivate black bears not to go diving into dumpsters, first you have to think about why they do it. Telling them to stop isn't going to help. There has to be some incentive for them to alter their behavior.
