We don’t need meat to survive but eating meat (in moderation) makes it much easier to ensure you get all nutrients you need. Especially when you have children, it’s very dangerous to attempt a vegan diet. Also, killing animals is part of nature and happens all the time. What’s not natural, and what’s unethical, is making their lives miserable before that happens.

And speaking of ethics, you just said two comments above that we should spread this disease worldwide, and were fine with people dying from it just for following the diet they’ve had all their lives. Not very consistent in my view.

hardly anyone kills animals at all, except pests or by accident
