No need to be pedantic. I'm pointing you to the Vegan Society, who actually created the term vegan. I'm merely trying to educate you on the topic. The dictionary definition is simplifying an entire philosophy, otherwise vegans would also be okay with horse and dog races, horseback riding, using animals as labor and other forms of animal exploitation.

Quote of the important part of the article (highlights by me):

The word vegan was coined by Donald Watson from a suggestion by early members Mr George A. Henderson and his wife Fay K. Henderson that the society should be called Allvega and the magazine Allvegan.

Although the vegan diet was defined early on it was as late as 1949 before Leslie J Cross pointed out that the society lacked a definition of veganism and he suggested “[t]he principle of the emancipation of animals from exploitation by man”. This is later clarified as “to seek an end to the use of animals by man for food, commodities, work, hunting, vivisection, and by all other uses involving exploitation of animal life by man”.
