Jordi Casamitjana, author of "Ethical Vegan," discusses the importance of effective communication in spreading the vegan philosophy. He highlights the top 10 vegan messages that help communicate the values and principles of veganism. These messages include "No, Thanks, I'm Vegan," "Go Vegan," "We Want Animal Liberation," "It's Not XXX, It's Violence," "All Animals Are Sentient Beings With Rights," "Oppose All Exploitation," "Stop Speciesism (Otherism)," "Dairy Is Scary," "Veganism Is for Everyone," and "The Vegan World Is Possible." By utilizing these messages, vegans can effectively communicate the core principles of veganism and inspire others to join the movement towards building a Vegan World where all sentient beings are respected and free from exploitation.
