It's not about what their kids can read, they don't want anyone's children to read them. The entire point is to limit the perspectives available to children so they don't grow up seeing LGBTQIA+ people as people who deserve rights like """""normal""""" (in their mods) people get. They want them to go back into the closet where they don't have to think about or, dare I say it, admit to themselves that they are interested in those """"""yucky"""" behaviors.
These people freak out over the increase in LGBTQIA+ identification, as if people didn't previously feel this way, they were just too scared to say anything because they didn't want to end up like Matthew Shepard.
