Disclaimer, this isn't true for everyone, but as somebody raised southern baptist, I think this image is missing the point.
The biggest risk for Christian parents having their kid go to a drag show is they might end up questioning Christianity, and rejecting it.
They're not wrong about that risk, just about the morality of it. They want to have their kid indoctrinated, but only into the things that believe. They see anything that takes their child away from Christianity as evil.
Those kids might realize that there's people out there who don't do what the bible says - they crossdress, they're gay, they don't go to church, they don't believe in god - and yet, they're good people.
The Bible isn't against any of those things. They chose to make their interpretation disagree with reality and now they have to constantly defend against reality.
Point is, it's a hard life being dishonest. That's why there's a rule against lying in that book.
Yep, there's a verse in Romans that shook me to my core as a church boy because Paul famous hater of women and gentiles, was saying that my priests and bishops were wrong and there were still good people out there literally separate (as we Christians see it at least) from God, and yet still reflecting that ineffable glory as an expression of themselves. Personally, though, those thoughts led me to Christian humanism and Humanitarianism as a movement at large which were also bad because of multi-cultural indoctrination lol. I think the organized church is just holding itself back from appreciating the fullness of creation and God by dragging its feet, ignoring that Christ never told us to condemn all things.
The ones in society screaming about indoctrination the most these days are just projecting. They want to be doing the indoctrination and any risk to that is "indoctrination".
Universities? Indoctrination. Queer people existing? Indoctrination.
Yeah, extremist lunatics come in all stripes. A bunch of right wing dipshit Māori churchgoers in NZ did a protest and haka against normal folks not too long ago.
