If you kick a puppy in front of your coworkers at lunch (please don't), they will absolutely freak out, while continuing to eat fish or sausage or beef or whatever. And it's taboo to discuss this hypocrisy because apparently food is sacred. Can't criticize someone's "personal choice" in today's society no matter how much harm and pain it causes.
For hundreds of years, social progress has been about realizing equality amongst conscious beings. Why is it so hard for people to realize this? Instead we have had incremental widening of rights: African Americans, women, LGBTQ+, - no, it's about the right to life and equality for conscious beings at the core. When you treat it like this, you realize how much of what we're doing is fucked up.
I guess it's true what they say: one death is a crime, a million deaths is a statistic.
Maybe I'm being pessimistic. But I feel like if benevolent aliens ever visited Earth, and saw how we torture and murder other life forms on the planet, we'd be the first ones they'd wipe out. Moral calculus would demand it.
