Besides the question I've always had for vegans is where do they get all of their complex B vitamins? I thought some of those can ONLY come from an animal source. While there are some conditions associated with overeating meat, there are also conditions of not eating enough like anemia.
And for the life of me, why is it abuse to use milk? If we stopped using cattle for their meat and milk and skins, we would stop simply raising them. Since they cannot survive in the wild, they would die off if left to their own devices. So in a way vegans are advocating the total genocide of cows, at least in countries outside of India.
I also had a total nutter for a boss trying to tell people in the company newsletter that eating meat is unnatural, that it wastes water, etc, etc. That guy had lots of issues. Small surprise his company had so much turnover. No one wanted to work with a crazy vegan with anger control issues.
