Earlier quoted context omitted.
I'm often confused by this as well, it's always been fairly obvious to me that other animals are sentient just like us (why wouldn't they be, their physiology is similar, they're descended from common ancestors). Modern factory farming doesn't sit well with me, but I still fairly comfortably eat higher welfare (free range, from reputable brands) or self-caught/hunted meat. It bewilders me that someone would eat meat…
Predators eat their whole life without wondering where it came from or what it implies about the world. It seems like the base state for every living individual, and is the most natural thing in the world. I think this is an important distinction to make, because if you don't make it you end up expressing contempt for those who don't think more widely rather than admiration for those that do.
Predators also put themselves at risk often, fail often, etc.
Factory livestock is very much removed from this.
