So, we need more gay people to have kids...

Actually, in the past, everyone was just like rabbits. They would simply enter any hole they came across.

So to suggest they were actually heterosexual is incorrect. They were simply "sexual".

heterosexuality and homosexuality are merely social constructs, in reality, they don't actually exist. While there is a biological preference for males and females coupling due to reproduction, there isn't really much else there.
