I've noticed that when you blame people for something (eating meat, for example), they're not going to listen, it's causing opposite reaction - to defend and continue doing the same thing. So, maybe it's possible to persuade people to stop eating meat, but it requires much wisdom and patience... I don't really try. When my friends ask me, I answer politely, but it's very hard, because when I say: "I'm do not want to kill living beings for food because they're suffering" it's already sounds like I'm blaming them. :(
