They joke, but I legitimately know people whose parents were the super Christian "any book about controversial topics is the devil and so are video games and TV" to the point where when she found out her daughter had Harry potter book, she burned every book of hers that wasn't directly religious.

Well guess who decided to "give them a try" since "the author clearly has the right ideas about life" since all her children are out of the house and the only ones who bother visiting are the two with kids (who would never admit it but they're only there for free babysitting and future help) and one who just doubled down into the religion despite witnessing the same bullshit as her siblings....

So yeah, this may have been intended as a joke, but they're closer to the truth than they might know.
