Sentientism discussion

#scifi often gets so close to #Sentientism's "compassion for all sentient beings"... easily and intuitively granting moral consideration to sentients even very different from the protagonists.

But it often fails too (warning: spoiler alert 🚨).

In one famous sci-fi duology a central plot theme is the horrific, dawning realisation that one alien species is farming and slaughtering another.

The cheery resolution is that some members of these two species negotiate a radically new, mutual relationship of x-species respect 💚

But... This joyous new way of life involves both species farming and slaughtering many other species of sentient being. But this is OK, and is never even questioned, because those other sentient beings don't have the capacity for language.

So near and yet so far 😢
