It's not objectively true at all. The sacramental act is the decision of the parents to have the child. It is the intent and the follow up action that determines the sacred, not some synthetic BS, manufactured from ignorance. Dogs can perform intercourse, there's nothing sacred there, because there is no intent and no understanding. There is both understanding and intent in the case of the team composed of the parents and the medical team. The effective knowledge, understanding and intent to create life makes the endeavor sacred. Poking away to no avail is simply stuck on stupid.
Masturbating to manufacture a new person with the help of lab techs. Isn’t that special.
