This is how you defined being vegan. You will now explain to me how you function without anything made of steel, rubber, vinyl, or plastic, which, incase you didn't know contain animal fat. You can claim that minimizing the usage of products that have some form of animal in them makes you self-righteous if you want. But if being vegan means you use nothing from animals in anyway, like you say, then I submit it is at the least, very very difficult if not impossible to be vegan in an industrial society.
