I admire your commitment and passion HC. I wonder, though, whether anyone has ever really been persuaded to become vegetarian? Were you? I certainly wasn't.
Sometimes, less often in recent years, a meat eater (usually male, often drunk, sometimes aggressive) has taken it upon themselves to explain to me why I should eat meat. It used to happen with strangers, at dinner parties. They seemed to take my meal as some kind of personal attack on them. All I wanted to do was get through the evening as invisibly as possible. I'd try to laugh it off, grow more and more uncomfortable and wait until it was time to go home.
Nobody persuaded or shocked me into becoming a vegetarian. Nobody will persuade me to eat meat. I think the best way I can encourage people to eat less meat is by cooking them something delicious and maybe by being healthy, happy and full of energy - if they ask me how I do it, I'll give them the recipe!
