It's a bit of a tall order to expect everyone to become vegan overnight. Conditioning is very powerful and most people believe that animals exist for consumption by humans, simply because they do not think about it, they just accept it as a fact. If we don't eat them they wouldn't exist, like that would be a bad thing. But if they think about it, then it's clear that breeding animals for food is a bad thing. Not to mention the fear and misery that must be impregnated in the animal sourced food, and how that is being taken into one's body.
