Vitamin B12 supplements are available at most pharmacies and grocery stores. That’s the only thing you really have to worry about with being vegan. Protein can be a worry if you’re not paying any attention at all to your diet, but just eat some beans and it’s all good. Or tofu. I like tofu better than beans, but I appear to be in a minority.

I’m not a fan of enslaving anything with a nervous system. Bugs might be more ethical to eat than cows, but they might not be. I wouldn’t play russian roulette with someone else’s head, so why would I take a risk like that?

No, I don’t like dairy or eggs. Egg laying chickens are kept in conditions so cramped, they’d peck each other to death from the stress if they didn’t get their beaks amputated. I have less of a problem with farm raised eggs. Now the modern domesticated chicken is a crime against nature, bred to produce eggs at a size and speed inconsistent with health and happiness, so it’s not like I have no problems with farm raised eggs, but I have less.

As for milk, well continuous milking of cows is bad for udder health, so most farmers let the cow rest for two months of the year to ensure good health and steady milk production over her lifetime. Unfortunately two months without milking leads the cow’s body to conclude it’s no longer nursing young, and milk production slows or stops. The farmers’ common solution to this problem is to keep cows in a more or less constant state of pregnancy, giving birth every year and then being separated from their young so the milk can be taken by humans instead of nature’s intended recipient. And a male dairy cow is useless except as a stud, so nearly all of the males born this way are killed at one week old. So out of the gallon of milk you buy at the grocery store, 50% of that milk took a dead child to make.
