I’m pretty sympathetic to vegans and vegetarians but I draw the line at them calling farm animals sentient
Sentience: the ability to experience sensations (in other words, to sense things).
So you’re saying that sheep and cows and chickens are blind and deaf, unable to smell and taste and sense touch?
If they are not able to perceive anything around them wouldn’t they fall down or bump into things a lot more? How would they find food?
Maybe you’re confusing the term “sentient” (which all animals with a basic nervous system are) with the term “sapient”?
