LA judge upholds state SSM ban

[H.E. VOLODYMYR ZELENKSYY]

Why did marriage in Anglo-American historical times exclude gay couples?  That's the question you need to answer. 

Why is that the question?  Wouldn't the larger question be, "Why has marriage been a predominantly opposite-sex institution throughout history until very recently, both in historical contexts where homosexuality has been condemned as well as those where it has been tolerated"?

Because the vast majority of people are heterosexual. I don't see how that's a question that needed answering.
