I think Christians need to be concerned about this because Christian care demands that we be able to help the people all around us who are struggling. We’re in a culture where Christians are the only ones that can teach moral sanity in the midst of the moral craziness we’re in.
Thus speaks a genuine-article Christian counselor explaining why he rejects “that a human being could possess a gender other than the one indicated by biological sex.”
Sex is plumbing, and that’s that. And those who don’t accept what a bunch of Bronze Age goatherders thought about it are just plain wrong. So there.
