"Science" recoils, for ex., at pretending a biological male could turn into a biological female.
"Scientism" says, "Hold my beer and watch this!"
Nope. Nobody says that one biological sex can become another biological sex in humans. That does happen in a number of animals species, but not in humans.
Biology sex and gender expression are fundamentally different categories. The problem isn't science or "scientism" as you call it; but rather being uninformed about these topics to the point of confusing them.
There is actual science, though it continues to be part of ongoing study, as to how biological sex and gender identity don't always align. And it's not because people want to pretend, it's because of how they are wired biologically.
I am biologically male, and I am also male in my gender identity.
A failure to address objective reality out of preconceived personally held "shoulds", as in someone who is biologically and genetically male
should identify a certain way and express their humanity in a certain conformist way, does not actually address the real world in a meaningful way.
I think it
should be comfortably warm and sunny all year long, but it's not. We have to deal with the fact that sometimes it's cold, sometimes it's rainy and cloudy, sometimes it's too hot. When we confront those realities, we adapt ourselves to them--we dress warmer when it's cold. We seek shelter from cold and heat.
Not everyone's gender identity aligns with their biological sex, and some people have ambiguous biological sex. Those people are real people. How you choose to respond to that is up to you.
Personally, speaking as a believing Christian, I think the Christian response to that should be in alignment and in keeping with the teaching and faith which we have received from the beginning. To believe and confess the Gospel of our hope and salvation, and living out our faith in Christ in obedience to God by following His Commandment, that we love Him and love our neighbor as ourselves.
