Its all bioreactionary stuff, really. Its always been about control and conformity to their idea of a """natural""" role.

Using technology to aid in reproduction is seen as bad because it's doing something """nature"""/"""god""" did not dictate you do as per their highly authoritarian worldview.

Basically anything that would let you have agency over your body is hated by these people, because their real ideology is one of control, social and physical conformity, and obedience (to "god", to what's "natural", to repressive social norms, to churches, to parents - these folks view children as property, to whatever hierarchy exists, to some strongman leader, etc. :/)

The same logic applies to something as comparatively minor as hairdye or piercings - they always freak out about that stuff, ever notice? - to something as major as being trans or the state of someone's uterus. Its all about control over people's bodies and minds and identities to what they may deem "natural" (or often "godly") (which usually involves hierarchies of prejudice as well as opposing any technological means to have control over yourself, and also opposing people's access to information and critical thinking skills - e.g. promoting internet censorship often of queer groups <.<, or opposing science & critical thinking education).

Anything that gives people the option to decide for themselves what they want - technologically, socially, informationally - rather than obeying some higher authority ("nature", "god", the state, corporations, parents, social norms) is opposed. Anything that demonstrates people have used those methods - such as any kind of transition stuff, miscarrages (because it "could" be due to abortificants nya), or the things mentioned earlier - is to be punished. Socially, monetarily, physically, legally, anything.
