I do not care what others do. I try not to judge. I am going to continue to eat meat and cheese. If you don't want it great, more for me. I do however find it funny that other than a few hardcore exceptions, leather shoes, belts, purses etc. are fine but a cheeseburger is murder. If you are one of the exceptions I can respect that.
Vegetarians usually are more focused on animal by-product-free foods, while vegans make it more of a lifestyle. For example, I avoid lots and lots of different skincare and haircare that have carbamide (excreted from urine!) amongst other things. I even only drink vegan wine! I'm know it's impossible to know exactly what is vegan and what isn't, but as long as there is Internet or an ingredient list, I try my best.
