Actually I think this can go for any bad habit. Take smoking for example. Stupid right? Just think of all the people it affects as well and think of someone who you love a lot that's way more important and fucking smoking and shit lol
The only part missing from this is that veganism is not a diet. It's about the non-exploitation of animals for food, clothing, entertainment, sport, vivisection, etc. Most vegans grew up with culturally indoctrinated speciesism and learned to break free from it. //// For me it started with the Unconditional love a pet.
