Most likely correct. In a few years homo marriage will have been normalized. We'll be fighting over polygamy and incest among consenting adults by then. Even those things are probably not a bridge too far for the public now that the left completely dominates our culture.
Speaking of incest, I recall a HS student asking a priest, in class, how Adam and Eve's sons produced children.
The answer involved ... Eve.
It's not that the left dominates our culture, sin dominates our culture. The worldview of leftism is relativism, which enables the rationalization of sin. Since leftists dislike the real world, and bummer ideas like right and wrong, they find themselves drawn to art and film and television, making up stories to tell us all about how sin is not really sin. In this way, They get to "make a difference" and "change the world".
And the sheeple consume it all.
