An insensate plant is morally equivalent to a rock. Neither is conscious, neither has anybody home.
It’s not a value judgement, it’s establishing the basis for what constitutes an “other”.
There is no “other” within unconscious entities.
Regardless, once again, even if you felt the grass was objectively as conscious or “valuable” (what does value even mean in this context?) as much as your children or your dog (and of course you don't, if we’re being honest, this entire line of reasoning is not in good faith) - then again:
> That said, even if you granted that every blade of grass and kernel of corn was fully as sentient as a human being, that would only strengthen the argument for veganism many times over as animals act as inefficient intermediaries for those plant calories, burning most of them and leaving only a small fraction in their meat. You’d kill far fewer plants by eating the plants directly.
