Does that make them vegan though ? Like hypothecially if we could ask cows for milk and they would be cool with it...would that be vegan? Or is mothermilk vegan for the baby ?. Im not shitposting I just have no idea about veganism.
If you could communicate with a cow then yes they could consent to having their milk taken then yes it would be vegan I guess, but you can't so it isn't. Any bullshit about how the cow consents because it walk to the milking machine or whatever is just nonsense.
Human breastmilk is perfectly vegan of course, since lactating humans can consent.
Breathing isn't vegan because there are tardigrades floating around on the air currents.
If I'm cooking food for the household and a hair from my head falls into it, is my food vegan?
