Since posting this video it has been brought to my attention that there are a number of people who disregard Gary Yourofsky's great work due to a number of his more extreme opinions.
This is a real shame.
Gary Yourofsky does has some opinions that I strongly disagree with. If you oppose his arguments after he has presented his evidence, or if you oppose veganism in general then he gets angry and he has been known to say that people who inflict rape and murder on animals, be it directly or indirectly, should suffer the same fate. He also feels that B12 should largely be ignored as we have some naturally. Both of these views are obviously wrong and both should be criticised.
This doesn't mean his amazing and insightful videos, fantastic essays and the great work he has published on YouTube and on Adaptt.org should be attacked or disregarded. His work on veganism is a great resource. He is articulate, passionate and, often, unassailable. As a resource he is invaluable and, along with other vegans and vegan works, has had a profound and positive impact on my life and on the lives of thousands of others.
Gary Yourofsky is a great man but he is also a flawed one. Promote his great work and views and his positivity and criticise his flawed views and negativity. No man is perfect and to disregard great, valuable and helpful work because of the creator's flaws is a great tragedy. Promote and benefit from good things and criticise and stop negative things. It's that simple.
