The main problem with veganism – the religion trys to make change through dietary self-denial giving them an illusion of change.
Real change comes from being and contributing real action into the world.
If you care about animals, you should become a caretaker of them (i.e. farmer), be a veterinarian, be an animal researcher, be an animal nutritionist, be someone who works at making the world a better place for animals.
Make the world practically better.
Most vegans live in an illusion because veganism gives them a false sense of altruism.
