Regarding dairy: first and foremost, we do not need dairy. No mammal, humans included, need to consume the milk of other animals, no does any mammal need to consume any mother's milk after the infant breast feeding stage. In fact, consuming milk, especially that of another animal, is not a healthy thing to do simply because we are not designed for such a thing. If that is not enough for you, remember that cows are mammals, and like all other mammals, humans included, they do not produce milk unless they are with baby. So, how do you get milk from a cow all year around? Either always keep her pregnant and with baby (and steal the milk from the baby for your own use) or inject hormones to fool the cow's body into believing that it is with baby. Also, where did all these cows come from? They have been bred in captive. That is, cows are either rapped or artificially inseminated. Baby girl cows are kept for their milk, the baby male bulls are thrown into the grinder and made into cat food (that's what they do at the local dairy farm near my home) or put in a cage and not fed any iron or mother's milk to keep their meat white and soft and then they are killed, chopped up and labelled "veal" (aka baby meat).
Eggs? Eggs are produced the exact same way milk is produced, only the product is different. Male chics are thrown into the grinder, females are injected or fed pellet food with hormones and also artificially inseminated to produce more chics. Chickens are like most all other animals, they give birth in the springtime, not all year around. Giving constant birth to eggs all year long puts a terrible amount of stress on the body and basically sucks their energy dry thus they live short lives before being sent off to become fried chicken. Doesn't matter if they are organic free range or not, the process is the same. Keeping them in a cage or allowing them to run around the back yard makes no difference in my eyes.
Anyway, there are so many videos out there that show the daily abuse these animals receive -- and why not? Who cares what happens to them anyway, because they are all going to be killed soon, so who cares how they are treated before their death? Right? Who cares if they have been in a cage their whole lives, who cares that their babies have been taken away and killed too. They are just stupid unfeeling animals -- they can't even talk, so they must be so very stupid, and they don't feel pain anyway, right?
Anyway, that's my take on it. And being vegan is not restricted in my view either. Sure, okay, meat, dairy, eggs, sea food... four things. I was never big on eggs, and never liked seafood.... so that narrows it down to two things that I removed from my diet -- animals and animal products. Two things. It's nothing.
