I'm not sure what's up with all of this mambo-jumbo on vegan principles. The issue is as simple as it gets:
All animals have the right to harm others for survival. Humans are animals. Humans do not require animal products, so humans do not need to harm other animals for survival.
Doing so is childish, anthropocentric and promotes discrimination based on inherited traits of all living beings, including humans. Of course, you are free to be as ignorant and as immature as you wish, when it comes to your actions. But do not dare call yourself an anarchist. Anarchism is an issue of consciousness/awareness.
The only point of veganism is to not inflict any needless harm on the world around you. I happen to believe that any person that consumes animal products because of being in a situation that requires them to do so can call themselves vegan, as long as they don't harm what is around them without doing so for survival. Anarchism that doesn't follow vegan principles is simply a mindless form of terribilism.
Now, to address the ramifications that have been discussed in this topic:
Humans are animals. We belong to the Kingdom Animalia. I hope we finally have that issue settled.
If anarchism is a workers movement, then feminism is a butch's movement. Just sit down or go home.
Harming other beings without doing so for survival is not a personal choice. Otherwise, randomly murdering a person would be also considered a personal choice that you are free to make.
Plants are required for our survival. I will never blame a lion for viciously murdering a zebra. I will never blame a person that has to hunt rats for survival. I will, however, blame a privileged person that promotes discrimination, indoctrination, consumerism, human slavery, worker abuse, extensive pollution, famine, etc. without doing these actions to survive.
Meat is unnecessary already. We don't need to grow it in vitro.
Veganism is not perfect and being a vegan does not make you an anarchist. You still support big companies, you probably still buy highly processed food products and you probably still use other non-animal products that are harmful. For example, we have the issue of palm oil: not an animal product. But it's not vegan either. You get the idea.
You don't vomit after eating meat because you cook it. If you can't eat something raw, then you weren't meant to eat that thing.
Veganism is not about animal rights. Veganism is about egalitarianism, refusal of ethical and legal hypocrisy and, shockingly, human rights.
Being vegan is less of a consumer activity because of the resources that were needed to produce the products. We grow food and use most of it to grow another type of food (animal), which ends up being less. It's a needless waste of resources.
We are over seven billion humans on this planet. The only way to produce enough meat for all of us is factory farming. You cannot eliminate factory farming without eliminating meat consumption.
Rape is just as natural as meat eating. So who's first?
There are tribes that have been living on vegan diets for over 5000 years. Saying people cannot live on a vegan diet is simply ridiculous.
Cows are social animals. They form bonds with other cows and animals of different species. Of course they participate in society, but your little indoctrinated brain cannot possibly comprehend anything that is not "usual" and "conformist".
I heard that human meat happens to be a particularly tasty meat type. If enjoying food is more important than critical issues of many, many kinds, then please, remove yourself from this plane of existence and never return.
Again, this is not an issue of how "natural" a certain action is, but how hypocritical it is.
No, killing a sunflower is not the same as killing a pig. Poor sunflower, sure. But I don't give a rat's arse about it. You know why? Because I need it for survival. I need plants to live. It's my right, as a living being on this planet, to do whatever I need to survive. Eating animal products is not one of those things. If I truly cared about animals in the way that you think, I'd be in the wilderness, saving rabbits from foxes. You're the one being ridiculous here.
Bees feel pain. Go home.
Peasants thought of veganism, of course. As mentioned previously, there are tribes living exclusively on vegan diets. Furthermore, my old, poor aunt, living in the Romanian countryside just became a vegetarian. Simply because she found it ridiculous to kill a creature for something that she didn't require. Also, I happen to know homeless people that follow a vegan diet. But that's beside the point.
Anyone who doesn't eat meat doesn't deserve any food? Talk about elitist losers.
Anarchism is not just about state control. But yes, it is related to the animal industry.
I find the life of a chicken to be just as valuable as the life of a human. If I'd save a human, I'd save a chicken. If I wouldn't save a human, I wouldn't save a chicken. Easy.
Adolf Hitler was not even a vegetarian. GO HOME.
You're implying that a person cannot possibly feel compassionate towards more than one species. But again, veganarchism is not about compassion. Funny that I used that term, I usually chose to reject it. Veganism is a part of anarchism. It doesn't need a special name.
hol·o·caust (hl-kôst, hl-)
1. Great destruction resulting in the extensive loss of life, especially by fire.
a. Holocaust The genocide of European Jews and others by the Nazis during World War II: "Israel emerged from the Holocaust and is defined in relation to that catastrophe" (Emanuel Litvinoff).
b. A massive slaughter: "an important document in the so-far sketchy annals of the Cambodian holocaust" (Rod Nordland).
3. A sacrificial offering that is consumed entirely by flames.
I will not stop making relevant points only because you feel uncomfortable. Animal slaughter is a holocaust by definition.
And that's about it. I didn't quote any of the things I responded to because I'm lazy. Sue me.
And in response to the original question:
No, you cannot be a proper anarchist without following vegan principles.
Yes, you can be a vegan without being an anarchist, so my anarchistic side is not sympathetic towards all vegans.
