The Pupa vegan comics exist to make people laugh and reconsider their position. Some people will not find it funny, some people won't connect at all. There is no form of outreach which is 100% effective - if there was, then that's what everyone would be doing. I know that the comics do have an impact, because I keep getting people writing to me to say they've gone vegan after really thinking about it since seeing the comics. I make them this way so they're accessible and simple.
But more importantly - if you aren't vegan and you're trying to tell me how best to get the message across - then just tell me what to say to you, and I'll say it back, and then you'll go vegan right?
