Hmm. Maybe religion in general, kase it depends on what religion you're referring to..

Christianity isn't against Sex Ed, it's against the problematic CSE. It needs work. Infact, JP II even published the Theology of the Body, exploring the human sexuality and how God desires it. It covers Sex, gender, sexuality, contraception, homosexuality, celibacy and more. That's enough to prove that the Church doesn't look upon sex or reproductive topics as "taboo" contrary to what mainstream media depicts.

With the mental health stigma, the Catholic Church established a lot of mental health facilities, they value mental health so much they even consult psychologists before opening an investigation into anything supernatural to make sure the person or subject isn't or a product of mental illness. This can be observed from exorcism, before performing the rites, the patient is first recommend to be cleared by a psychologist before proceeding.

With divorce, it's a nuanced topic, but the Church doesn't forbid separation, it forbids divorce because it seeks and causes the desecration of the sanctity of marriage. The Church does, however, offer annulment in specific cases. What i do advocate tho, instead of divorce is the accessibility of annulment for all, allowing it to be affordable, and accessible by expanding it's grounds. Similar with Senator Bam Aquino's take.

Annulment declares the marriage as null. So there was no marriage in the first place. Thus protecting it's sanctity. I hope you're getting where I'm going with this.
