I never really understand why people find it so entertaining to make fun of vegetarians and vegans.
Their choice results in less suffering, plain and simple. Maybe you aren't willing to change your diet, that's your decision. But if others are willing to put effort into changing their diets and become vegetarian because it's in line with their values, that's admirable and should be applauded.
Please don't make fun of people who put time and energy into pursuing their values. Not if you don't see yourself as a bully.
