Actually, going vegan, far from ruining your Thanksgiving, should help bring you back to the authentic meaning of the holiday: gratitude. Since I won't eat a dead turkey that has had a miserable life, I can have a more honest, authentic, and joyful Thanksgiving.
And I'm grateful that I saw through the lies of the meat and dairy industries, and that people like Foer are exposing those lies!

Each time you bite a piece of meat, you are aware deep within your mind (almost unconsciously) in what cruel manner the animal was killed. But you willfully suppress that knowledge so that it want come to your conscious knowledge.

Practise this over a period of time and you become hard hearted, insensitive to cruelty towards others. The ultimate result is that man becomes a cruel animal himself, as is well demonstrated all over the world today.

I just finished the book "eating Animals" and it was fantastic. Of course I was already veg anyway but I'm glad Mr. Safran Foer and others like him are getting the truth out - people need to know!
