This was not my experience at all. School libraries provided a wide variety of content, books spanning many genres, time periods, etc. I read a little bit of everything and am grateful to have been able to experience that, instead of being constrained to whatever some adults may have thought would have been "good for me".
It's true that I had access to public libraries with this same variety, so what happens when those are the next target? I couldn't afford to buy books on Amazon. Would I just have been forced to read e.g whatever religious or political media that's been approved for my consumption?
