I'm not a vegetarian. But I have both vegetarian and vegan friends. I like to have people over and when I have them over I must feed them. Not necessarily because of etiquette standards or because they're hungry, but rather because it is ingrained into my very soul that when you invite people over you feed them (even if they're just meeting at your place to go somewhere else, like dinner, you still offer snacks). So, I learned to make some vegetarian and vegan dishes without even having to use chicken stock!
I've missed the big deal about chicken stock apparently as the only time I use it because a) the recipe tells me to do so, or b) I'm making chicken salad (I boil chicken in chicken stock, keeps it from being too dry). I don't even think I have any in the house right now. But I'm not a chef or connoisseur of much of anything. I'm pretty excited when I complete an entire meal without starting a fire or burning something. Even better when everyone likes the food I've cooked.
The whole thing sounded troll-y to me. And if not...then people I don't want to hang out with. And I eat meat.
