In no way, for those who consider everyone of equal value.
The Bible has many disturbing stories and isn’t appropriate for children in my view, having read the whole thing as a kid.
For those (i.e. bigots, fascists, …) that feel humanity is a hierarchy of value where the in group is at the top and the out group are below that, they are opposed to validating the perfectly normal and human experiences of people with a range of gender identities. For the subset of those that consider themselves Christian, they believe (without evidence) that the Bible is somehow better for kids than allowing them to be themselves and be validated and accepted by others.
A friend of my kid is exploring their gender identity. We have known the family since they were a baby. My wife is friends with the mom. They are religious we aren’t. Unfortunately the mom insists on rejecting their identity and new chosen name. I personally cannot comprehend how one can prioritize anything over my own child’s happiness.
