So, your claim is that in the settling of North America, where there was no government, people did not get married?<quoted text>
The govt has always been involved in marriage, even before the US came to be; they just did it through the official state church which married people and controlled the right/benefits which came from marriage.
Since the US doesn't have an established state church they had to create a civil marriage union to grant the rights & benefits of marriage. Marriage establishes a legal kinship between unrelated individuals.
Homosexuality wasn't accepted by society out of animus/bigotry/ignorance/etc, so it's not suprising gay couples weren't allowed to marry.
Women have been roughly half the entire population since the beginning of time, yet they were considered the legal property of their husbands and couldn't vote or own property etc. Why didn't women have the equal rights they do today in most countries?
If "Homosexuality wasn't accepted by society out of animus/bigotry/ignorance" , why was it so consistently condemned across societies around the world despite huge differences in religion and morality?
And yes, women were treated as inferior due to the biological hierarchy that the strongest dominate and women are physically weaker. That was fixed as thought became more important than strength, just as gays were allowed to openly exist in society. Still, men and women ARE treated differently (for example in military physical fitness standards) because they are different. Likewise, gay marriages are different from heterosexual marriages.
