I'm no US citizen but I think it underlines the importance for (US) parents that have the means to do it to build their very own personal library (or to make one together with other parents, maybe), filled with books they want their child to read without any self-proclaimed censor telling them what their kid can and cannot read. It also tells parents how important it should be to encourage their kids to read, as widely as possible... by example, by themselves spending time reading (instead of doomscrolling?).

Public libraries and school libraries are a wonderful place, even those that are under the control of absolute morons (polite version), but they should not be relied upon as the sole access to books. Ever. Even less so for kids.
