My thoughts is that it’s simple.
If you think it’s ok to cause another conscious sentient being to feel afraid, suffer and die so you can eat its corpse than that’s what you’re going to do. You’ll be ok with causing pain and suffering because you like the taste of a dead body.
If you’re not ok with causing a sentient being to suffer and die then you can eat just plants, algae and mushrooms and take a vitamin and get absolutely everything you need. Fish get their DHA and EPH from algae. Or either fish eats other fish that ate algae. For $20 I can get double the amount of DHA and EPH that I need. For $8 I can get b12 for a month.
So primates most closely related to us like Chimps and Bonobos eat round 96% of their diet as plants. Gorillas and Orangutans eat more than 99% of their diet as plants. These animals are also far more predatory than humans are.
After all, if you think being vegan equals pretending to be prey then by all means be a predator. To chase down an animal. Grab it and tear into with your “claws” and almighty “canines” ( which is just a name btw horses have them too and theirs are far bigger ) and chew through the fur, eat the raw bloody parasite infected flesh and enjoy it. Smell roadkill and drool over how nice it smells. If we are going to be like so many of the animals then get ready for Andrew Tates alpha male mentality to rule over you. You’re either strong enough to fight off the top dude or you can sit to the side and watch him kill your kids and get your women pregnant to have his offspring.
As for things like the Mediterranean diet that’s also debated. It was debated 20 years ago when I was in college taking nutrition classes for 2 years and it’s still debated now. The debate centers around what actually makes it healthy or not and comparing it to who?
This medical doctor and dietician dives into the diet.
There is also some terms that have been being slightly hijacked lately. Take vegan and plant based. Veganism is a philosophical and ethical stance against causing animals unnecessary suffering and death through exploiting them as goods or entertainment. Plant based is not the same as veganism because plant based is just about what the material is from. Someone can have a plant based diet but not be a vegan because they support rodeos, they wear leather from livestock and so on.
There is also a good book on fish and how intelligent they are and how they even have their own personalities, just like bees do.
“what a fish knows” by Jonathan Balcombe.
Also when we look at coprolites of prehistoric men most of the concepts people get is from Hollywood movies or a very small slice of their life. Like they ignore 300,000 of humans for a time span 20,000 or so years ago. Even then, they act as if most
Did not remain in tropical spaces. There is a reason why modern white people popped up just like 10k years ago. Blue eyes even evolved before pale skin. Anyways the coprolites are often around 120g of fiber meaning roughly 7lbs of plants and mushrooms a day. Some even showed dental studies indicating almost no or any animal flesh eaten
But really it just comes down to this.
If you would not like someone to do it to you, your kids or your pets than you should consider not doing it to others. Golden rule after all.
People often fall back to the Bible to defend things that we now know is bad. Take slavery. The Bible never says it’s wrong for me to go to war and bring back a woman to be my concubine and for another person to be my slave. But I should be a good master. The Bible never says it’s wrong for me to decide to make my daughter marry a man because he’s giving me a really nice set of goats and a cow.
A lot of people also like to bring up… but what about is you’re on an island or living in some hellish place of ice and not plants… who cares that’s not you right. You can get every single macronutrient, micronutrient, vitamin you need without causing an animal to suffer. It’s also cheaper. You eat meat because you want too, not have too. You eat meat because you feel your tastebuds are more important than beings being hurt for you.
Also Angela Davis, a civil rights icon, goes into how animal abuse and liberation runs parallel to what is happening to marginalized communities. Babies are separated from their mothers. Many slaughterhouse workers get severely injured, depressed and so on.
One of the main reasons why I am walking further and further away from Christianity is the abuse Jesus carried out against animals though.
