Ah, so men and women didn't fall in love in, say, 3000 B.C. They had a fundamentally different nature than us enlightened folk in 2008 who mystically evolved the ability to fall in love with each other in the time since then. Nah, back then marriage was all about contracts and cattle and land ownership...and that's why slaves never got married, doncha know.
This isn't the "history" of marriage...it is some modern theorists' silly projection on the history of marriage. And judging by the argument, a person who a) didn't like the institution very much and b) believed this Marxist twaddle that everything's about money.
I never said people didn’t fall in love but there is a HUGH difference between “falling in love” and marriage. Hopefully, the two go together but not always.
And if its all about “falling in love”, then you should have no problem with two men or two women falling in love with each other.
And throwing such buzz words as “Marxist” does nothing to support an intelligent, rational discussion.
