Please stop labelling us veggies as smug. The vast majority are, y'know, normal folk going about our daily business and just choosing not to eat certain stuff. I wouldn't dream of telling someone not to eat meat, yet I've had loads of people twatting on at me over the years - 'You'll make yourself ill if you don't get some steak down you', 'Bet you could murder a bacon sarnie', 'I bet you're going to lecture me now aren't you' (erm, nope) and my personal favourite 'Is that why you're so small?'. Yaaaawn.
Seriously, eat horse, cow, dog, whatever. Just leave me to eat my tofu in peace will ya.
