Alternative Ethical Eating Lifestyles
From Philosophical Vegan Wiki
Although Veganism is something we strive for society at large to accomplish, we gladly accept any reduction in the consumption of animal products. A person who is making an effort needs to be congratulated and encouraged (especially in a society where meat-eating is the norm), rather than ridiculed for not going far enough.
Of course, we should be critical of people who claim that they are doing enough and don't need to do anything further (which extends to many vegans as well), but every meal without meat in it is one step towards a Vegan world. This article lists several different ethical dietary lifestyles that are also viewed to be done out of the concern for animal welfare.
