Don`t know what your anger issue is. But you were wrong. and shown you were wrong. It`s your issue if you can`t accept that. Show some humility and you could be a lot better at learning and progressing rather than than lie to yourself and think you are right. Thats a detriment to you only. Websters, has two entries for VEGETARIAN and VEGAN. All vegans are vegetarians but not all vegetarians are vegans. Thats the difference. Hence despite longer history of veganism, The term was first stated in 1944, Donald Watson, founder of the Vegan Society, coined the word vegan in 1944 as a statement against vegetarians who ate dairy and egg products. If you claim the word was entered into use in the "seventies" That would make the term at minimum , 41 yrs of use. That is not a "new" term as you claimed i made up. Vegetarianism has been documented for centuries at least, Its use as a descriptive dates back to mid 1800`s You can`t claim that a new term either.
