Maybe actually try to think about it once, neutrally. If you spend any time around animals like dogs, cats, horses or even cattle, you’ll notice they exhibit signs of a character: they show affection, have bad mornings, nightmares, favourite foods and care for their offspring with what you’d call love in humans.
This pretty clearly indicates some kind of sentience, meaning a feeling of subjectivity (all of this is solidly backed science-wise, by the way) and emotions. Now those animals might experience reality very differently from us, but that doesn’t even matter. What matters is that they experience some kind of subjective reality.
Is it really too foreign of a thought to try and minimise the number of animals that have to live in agony until they are killed, just for that tasty steak on your table?
I don’t want to control your life. I believe this is a logical conclusion thinking will eventually get anyone to, given the effort - and moral integrity.
