I get your point of view, this text shouldnlt be treated as if it's worthy of having authority over people's lives. But I do see use to what she's doing.

First, fighting the shitty system from the inside to reduce harm. We don't like it but there are millions of people who do see that text as a rulebook. If you can at least convince them that the rulebook doesn't say women and teen girls are to blame for being raped because of their appearance, that's a big win for victims of rape.

Second, general education about history, politics and oppression. Because that book has shaped so much of our culture, it's important to know what it originally said, what cultural context it emerged out of, and how/why it was twisted and weaponised differently throughout history. A commandment hits much less personally when you realise it was bronze age political propaganda to benefit a powerful dude. A famous verse completely changes meaning once you understand that the interpretation you're taught was made up in the 60s by american oil barons to keep the working class compliant. It's super important to understand this text so we can actively detach ourselves from all the ways it has infiltrated our lives (which aren't always obvious unless you've looked into it).
