You're joking, right? Plenty of herbivores have teeth or tusks...something they can fight with. If they didn't, than they'd quickly be hunted to extinction. Our cainines aren't for ripping flesh and tearing arteries. They're for fighting. As for being made as omnivores? What exactly do you know about our physiology? Do you even know our stomach acids PH level?
With Jake Shields, his career is quite an accomplishment. Fighters who have followed his example remarked that they feel stronger in fights. Look it up since you probably don't believe me anyway.
As for your little hunting experience? Yes, you use knives and guns. We don't have claws, or beaks, or proper, neck breaking jaws of teeth. We need to cheat to keep this habit up. And we've been cooking the meat just so we can tolerate it. Why must meat eaters go on about the natural order when our methods are far from natural?
For your plant argument, I don't know what's worse. Taking it a step beyond sensation by saying they might have emotions, or using it to point out the cruelty of veganism. You've basically acknowledged that suffering is not something anyone should cause, even if it was sarcastic. And while a vegetable having feelings or intelligence is doubtful, this is confirmed in regards to animals.
As for hunting to survive, this isn't an apocalypse. If you have the money for the devices and power neccisarry to play Skyrim and use this forum, you can spend it on some quinoa. Or even meat, if you insist on eating it.
As a minor note with bugs, I never really kill them. Squashing and flushing them always seemed like an unnecessary experience when I can just dump them outside.
Sorry if I sound like an ass. Flawed points put me in a bad mood.
They don't have canines for self defense, tusks are meant for self defense and mating competition, not for chomping food. Stomach acids are made for one purpose, to dissolve what's inside the stomach, that doesn't constitute whether or not one is a herbivore. If humans were built as herbivores, we wouldn't have hunted mammoths and other animals in the early days. We would've eaten plants only, there is no herbivore that goes around eating meat. Claws do not constitute a meat eater, the teeth and diets do. What is used in their digestive tract is all a part of it but the teeth plays the biggest role. A Brachiosaurus isn't going to kill and eat a Deinonychus because it's smaller and they just feel they should eat it or want to it, they can't. If they try to, they can't tear at the meat like canines and other carnivorous teeth would. They can and will kill opposition or rivals, but they won't eat them. I haven't seen or heard of a deer eating a smaller animal. Guess what, those canines are meant for chomping and tearing, look it up, biting can be a move yes, animals use it as in self defense, but most animals with jaws that can open and close can bite with different levels of pressure and bite force, you don't need canines to bite someone. They're not developed for biting in self defense, they're useful to enhance the bite but it's the jaw muscle that determines the biting force.
Our tools and our ability to make and use them is not cheap, we as well as primates use tools to help with hunting and other tasks, to say that's cheating because we lack the claws and other natural weapons is stupid since we design it using our brain power. It's because of our brain power and hand-eye coordination which put us and kept us on top of the food chain. Not strength, not our hands though they do play a pivotal part in our development. There are many attributes to cause a fighter to say they feel stronger in fights, it's called nutrients which can be taken in many foods including meat, there's also things that boost morale, fear itself, or to make someone fight for a purpose. That's how humans won wars among themselves as well. The reason why they feel stronger isn't because they stopped eating meat, it's because they see him as idol/role model, they followed his example and they feel stronger because they're following a winner's diet, same is said in other martial arts where they follow Bruce Lee's diet and training which most of Bruce Lee's work is one of the main reasons how MMA got started to begin with. It's whatever works for the personal trainer, if it doesn't work for them it won't, this doesn't mean it's flawed or terrible but just not meant for them. Many MMA fighters even mention how amazing Bruce Lee and he wasn't vegetarian or a vegan. Everything about us and where we are is thanks to everything mentioned about where we came from, you can't just ignore that or say it has no effect or place in this debate. I've had Skyrim for about a year now, I've had this laptop for far longer when I was still in the military, the internet is free due to local hot spots.
Vegetation has a different build and have different systems, they will react differently and yet the same to danger, we're not talking about getting up and moving, we're talking about chemical reactions which even animals have as well. Musk, skunks have fumes, toxin/poisons/bacteria, puking up, etc. Plants have their own reaction as well and some show it as well. Bravo to you dumping them out, but that's just you, many others still squash them and denounce them as living beings as well as plants. These botanists are also reputable folks who shouldn't be ignored because they state something you don't entirely agree with.
Plant Physiology, they do have neural chemicals though.
Science and Politics behind it.
Plants can feel as confirmed by this page among many.
More into plants here as well. Because animals show it, it's easier to say they can feel and react but plants can't.
Your flawed points should've put you in a worse mood.
