I was 18 at the time, and my older brother went vegetarian. We both lived at home and every mealtime he used to sit there at and say "meat is murder", "you say you love animals but you still eat them", "you're a hypocrite for eating animals" etc - you get the drift.
Did it work? Did his constant haranguing make me into a vegetarian?
A big part of me agreed with what he said, but you know what it's like when someone attacks you - what do you do? You fight back. You refuse to give in. You refuse to change. You refuse to let them win. And you hate them, and their ideology, with a passion.
After about 3 months of telling me what a horrible person I was for eating meat, he gave up trying. And instead he handed me a copy of Peter Singer's Animal Liberation and asked me to read it.
So I read it. And I have to say that, to this day, it is the only book I've ever read that's made me cry. Reading that book made me ashamed to be a member of the human race when I realised how badly we treat other animals. And I decided there and then - "Not in my name".
That was 36 years ago. I've never changed my mind, never even considered it for a moment.
And I always remember how my conversion came about. Not by being bullied, not by being told I was wrong, and horrible for eating meat. Not for being put down for not doing enough. No, that delayed my decision by 3 months. More animals suffered because of that attempt to persuade me I was wrong. It was a sobering lesson for me (and maybe for you) about the best way to talk to others about animal suffering.
