mmm food for thought here. .. i agree that asking others to change can often cause a push back resistance.. I LOVE to lead by example.. and find that often is the best inspiration for others to alter their ways..
i mean for example.. compare telling someone to GO VEGAN as opposed to making them the best tasting vegan dish they've ever eaten! i know which one would inspire me most!
This would be more effective and gentler than arguing the morality of consuming meat. :)
