The third building block follows naturally from the other two. If the binary of male and female is God’s idea, and if we are meant to embrace, by divine design, our biological and creational difference as men and women, then it stands to reason that the confusion of these realities would be displeasing to God. And so we see clearly in the Bible that men should not act sexually as women (Lev. 18:22; Rom. 1:18-32; 1 Cor. 6:9-10), that men should not dress like women (Deut. 22:5), and that when men and women embrace obviously other-gendered expressions of identity it is a disgrace (1 Cor. 11:14-15). We do not have an inalienable right to do whatever we want with our physical selves. We belong to God and should glorify him with our bodies (1 Cor. 6:19-20).

I’m going to have to reread Deuteronomy 22 to see where that came from.
