The recent thread about dinner guests unearthed more of the hostility toward those with restricted diets (especially vegans) that I've noticed frequently on Serious Eats. While some vegans/vegetarians are aggressive or political, most are making a personal choice they don't impose on others. Those of you who deride vegans/vegetarians in your posts-why? Have you had specific negative experiences with veg folks? Vegans/vegetarians - how much do you encounter this in your daily lives?
