Oreos have palm oil, which is now considered not-vegan by many because it affects orangutan habitats. Vegans are generally nuts. I ate plant-based for a year, and other vegans put me off it. At some point I was like, "Fuck it" and went back to eating tuna once in a while.  The one thing you'll notice about vegans is that most are very extreme. They either will eat next to nothing, some will only eat like a head of lettuce with 2 or 3 dates for dinner. Their sodium levels actually get too low, so they dry celery in the oven to make celery salt from scratch. Other vegans like this one graze all day in imitation of cows and then can't understand why they are huge. I bet she eats a lot of cashew cheese etc, which is all insanely caloric.  There just aren't a lot of people who call themselves vegan doing something normal, like eating a peanut butter & banana sandwich on vegan bread for lunch. The portions are all pretty extreme.
