“Foes of allowing same-sex marriage might note that there’s been no noticeable breakdown in the fabric of society that can be attributed to extending the right to marry to people who share the same gender.”
thats sort of like the pot smoking study that came out in the 70s. No noticeable difference in someone who smokes pot for 10, 20,30 years. whatever the number was. The problem was their test subjects had been smoking pot for their entire lives and pot had been smoked copiously on that island for generations. So whatever difference might have been noticed had already occurred. If I am 40 years old and have been smoking pot since before I was born, and you test me for 10 years, you likely won't see much of a difference.
Somewhat similar situation here. These people have been living together and having sex and doing all the relationship intimacies, so the piece of paper isn't all that big of a difference if you are trying to understand the effect. The effect is a cumulative thing and has to be studied over large numbers of generations to be understood.
The similarity in climbing are the small mistakes that singly don't lead to catastrophe, but together can.
And Please, you don't need to flame me. I'm just explaining a viewpoint. It doesn't mean that I agree with it. If you want to change something, you generally need to understand it.
The viewpoint of some spiritualist would be over millions of years. 10 years would be next to nothing in that time frame.
