Yep. The goal of all of this this is to force people into straight marriages because that's all that matters to religious zealots.

They know that if kids practice safe sex they won't get pregnant and 'shot gun marriage' rates will go down.

They know that if kids discover their gender or sexual identity is non-cis, non-het, or non-monogamous that they might not wind up having a traditional marriage.

The know that people who only have 1 partner in their lifetime are much, much less likely to successfully leave an abusive partner, meaning there's a higher rate of divorce if people learn that having multiple partners in your life is normal and okay.

They know that kids who are educated about healthy sex and consent in relationships are less likely to go along with a child marriage or an assigned marriage.

They know that removing sex ed means more teen pregnancy, more intimate partner abuse, and more child-rape. For religious people whose only goal is to get young women into marriages, those are good things.

Example: An actual elected official in the state of Missouri defending his stance that "Parents Rights" includes the ability to marry off their kids to adults at age 12, because "Do you know any kids that have been married at age 12, I do, and guess what, they're still married". https://www.youtube.com/watch?v=9H6UJ-uCrgc

These people legitimately believe that it's morally correct to kidnap a 12 year old girl and force her to be entirely subserviant to, and dependent on, some pedophile husband who controls everything they do, because them being trapped in that awful situation means that there's one more marriage in the world.
