2/ There are two ways people use the word vegan. One is as a concept that is a useful direction to move your diet in, that delivers potentially massive payoffs where animals, health, and environmental sustainability is concerned.
3/ @bittman once shared a nice metaphor with me. He thinks of veganism as a goalpost. If your favorite NFL team moves the ball 30 yards closer to the goalpost, you cheer. You don’t boo them for not scoring a touchdown on that play!
