Why are vegetarians/vegans so arrogant?

Vegetarians, and their Hezbollah-like splinter faction, the vegans, are a persistent irritant to any chef worth anything. To me, life without veal stock, pork fat, sausage, organ meat, demi-glace, or even stinky cheese is a life not worth living. Vegetarians are the enemy of everything good and decent in the human spirit, and an affront to all I stand for, the pure enjoyment of food. Why do you guys hate humans, your own species, and think dogs and birds should have more rights than us? Meat is an essential part of the human diet that we can't survive without.
