Same-gender marriage is nothing new either. Couples have been trying to have their marriages legalized for over 40 years.<quoted text>
I pointed out legal interracial (black white) are nothing new, and existed prior to some of the bans. SSM is a modern invention.
How many races/ethnicities are there? Same number as there are sexes?
And I'm sure that when interracial marriage started here in the U.S. it was considered unthinkable to the vast majority of citizens--just like you think same-gender marriage is unthinkable.
Now we don't even give interracial marriages a second thought.
Marriage laws have evolved in this country. There is no denying that.
At one time it in the U.S. was legal for people to marry as young as 12 years old. And in some parts of the developing world, that's still possible.
You guys seem to think that marriage has been static and unchanging for thousands of years. But you know that isn't the case.
Whether it's been between one man and one woman, one man and multiple women, one woman and multiple men, a man and a man, a woman and a woman, one man (or woman) and deceased people (look up "ghost marriages"), arranged marriages--the fact of the matter is that marriage has looked very different over time and throughout the different cultures on this planet.
That we are evolving marriage to include same-gender couples is just another example of the changes in the definition of marriage.
