I honestly don't understand how banning books is constitutional. Like, I definitely don't want it to go before the SC any time soon, but books should be protected speech.
The books are free to purchase, own, and sell by the general public. The books are not banned.
What they are talking about is selecting what reading material is to be taught and available at schools. Such has been a thing since schools have been a thing. Schools do not have infinite time to teach nor infinite space to house books, selection criteria necessarily exists.
They are absolutely being banned. Universal bans and not allowing things to be published or sold at all is not the sole definition of banning things. That's not the only way to define banning. It can be small, local, regional, or unilateral. There are many different places or ways a ban can take effect. The books are being banned from schools and libraries in some cases.
If I ban something from my house, it's still a ban. If it's banned from the neighborhood, that's a ban. If it's banned from only my kid's school, that's a ban.
I don't get why some people think a national ban against the publish and sale of books is the only definition of a ban.
