Idk about that, with even just a few chickens you could feed a family of humans reliably. A creature’s “value” ist not based on whether or not they’re as smart or capable as humans. When I was growing up we had some chickens and they fed us with eggs for my entire childhood. That’s some value right there.
On the other hand, we humans are devaluing their lives by mass-producing and mass-killing them before they’re even grown up and able to show their value.
Meanwhile, I’m pretty sure my value is negative. I don’t contribute anything to society, I simply consume and pollute.
It’s all relative.
Honestly I disagree.
Should a book detailing how to kill yourself with household items be in a school library? Sometimes it’s about protecting people from themselves.
I do agree that Mein Kampf should not be banned (and funnily enough, contrary to popular belief it never was banned in Germany), but please don’t put it in every library. I would feel weird handing a child a copy of it, even if it was annotated. They lack the critical thinking skills and context surrounding it, and might misinterpret its contents. Anyway I’m not saying I’m right, that’s just my opinion.
PS: I like your phrase “it speaks for itself” because in my eyes, all books “speak” to you, but not all of them say the right things. It’s up to the reader to interpret it, and not everyone is capable of that.
