Well...if the subject was polygamy...and Carrie Underwood said in regard to a polygamist: “As I married person myself,” she said, “I don’t know what it’s like to be told I can’t marry somebody I love, and want to marry. I can’t imagine how that must feel. I definitely think we should all have the right to love, and love publicly, the people that we want to love.” ...“Above all,” she said, “God wanted us to love others. It’s not about setting rules, or [saying] ‘everyone has to be like me’. No. We’re all different. That’s what makes us special. We have to love each other get on with each other. It’s not up to me to judge anybody.”
I think that would be quite clear that Carrie was promoting polygamy.
And, as a matter of fact, her statements were sooooo open-ended, that they actually DO wind up embracing ALL kinds of illicit relationships: Polygamy, polyandry, bigamy, affairs, etc.
So glad I don’t depend on Underwood as my moral compass. :-)
