A note to all hard-line vegans: If you want to do something to improve the welfare of the animals we raise for meat, engage people in discussions of humane farming practices w.r.t. livestock. Most meat-eaters you talk to aren't ready to give it up. So ask yourself: Would you rather live in a world of factory farms, or a world where animals are raised and slaughtered in the most humane way we can manage? Give up on the idea that you'll convert everyone you meet to a vegan, and you can still do a lot of good in this world. When you take hard-line stances like the poster above, you alienate your meat-eating audience and end the conversation.
