How about meateaters than make you want go vegetarian? In my experience as soon as meateaters know you want the veggie option they leap on to you with stuff like 'don't you know vegetables have feelings' or 'it's only natural to eat meat' blah, blah blah.
I know it comes down to personal experience and mine is no more notable than others, but all the vegetarians I know just get on with it and am not bothered with converting others.
